Let's protect the Moon! Again! In this fast-paced, lasers-everywhere defence shooter you'll mow down wave after wave of intruders in order to save a big hunk of space rock – and with all those cool upgrades and unlimited futuristic ammo, that will be no problem at all.

With simple graphics and simple sound effects to match, Alan Zucconi's entry for Ludum Dare 28, 0RBITALIS, suits itself well. Control the trajectory of a satellite in different celestial situations to have it orbiting the different objects for the entirety of the given time limit. No job is too big, and no gravitational pull is too small, so get your physics-themed thinking caps on and get flying!

A hero deserves as glorious a death you can find in the cold black of space, and you're sure to find it in Dramatic Execution, a Unity SciFi shooter by Abdullah Konash, Addictive old-school arcade fun, though be warned: it has a difficulty curve to match.

We only have one moon, so we must do our very best to protect it! So you'll jump into your Moon rover-type contraption, charge your space cannon and shoot some bad guys. with lots of upgrades, cool futuristic weapons and intense levels, That's My Moon is an action-packed, highly addictive shooter.

Well, Mission-Control Guy. You've screwed up a mission before. But now, with an asteroid headed towards Earth, NASA has decided to give you A Second Chance, in a space simulation by Major Bueno. While the "press the buttons in the right order" gameplay probably couldn't be sustained in a longer work, the high amount of easter egg clickables and subtle jokes makes A Second Chance a hilarious minigame.

Escape from a cursed alien tomb, find your crewmate and — if you're particularly fortunate — come out of it all with the brand new, uh, old fabulous Idol of Tavor as your lovely planetary parting gift. Metroidvania-style action and adventure await you in this sci-fi platformer.

The Naked Alien is an action platformer by Lucas Paakh that offers players a quirky encounter of the nude kind, as its titular being sets out to map uncharted territory. It's a little by-the-numbers, but The Naked Alien is strangely amusing, and definitely showcases the developers prodigious artistic talents.

Pilot your shuttle, conquer the galaxy, gather resources and upgrade all the things in Vasiliy Kostin's Galaxy Siege! If you enjoy planned upgrading, growing a system piece by piece to achieve today what you couldn't before, Galaxy Siege will most likely appeal to you.

Brent Silby's latest DHTML creation is Robot, a cool little retro shooter where Robot must fly and Robot must blast untold hordes of Alien Invaders. What's more, Robot must protect his pack of adorable Baby Robots. And since, as everyone knows, Baby Robots are Alien Invaders' favorite food, Robot is not going to have an easy time. A retro shooter with elements both familiar and unique, Robot is classic arcade fun.

Minigolf! In space! With explosions! And trance music! And lens flare! You'll find it all in Bomb Runner, a physics arcade game by Core Studios. Inspired as much by pinball as by golf, you must click, drag, and shoot your way through 24 beautiful levels. Some of the shots do seem to rely on luck as much as skill, especially in the later levels, but overall, Bomb Runner is an entertaining diversion.

In Sergio Alonso's shiny new bullet hell shooter, Boss Slayer, Ten alien starships have entered the solar system and you have 12 days to destroy these bad boys before they make their final approach to Earth. The game features an array of upgrades, of which each has a clear, immediate effect and it can be a lot of fun to watch your weak little ship transform so quickly into a beefy alien antagonizer. Boss Slayer isn't an innovative game by any means, but it understands the genre perfectly and serves up a smooth, streamlined gameplay experience.

A good story is great, but sometimes you just want to blow stuff up. In DN8: Pulse, a new shooter game from Squize, you are the commander of a puny little fighter who has to fight off swarms of enemy vessels if you want to survive. If you make it past the initial waves, you'll have the chance to upgrade your ship with extra shields, weapons, and even support pods and there are two upgrade paths, defensive and offensive. The clear selling point of DN8: Pulse are the graphics, done in Stage3D, which are unlike most anything you've seen in a flash game. The visuals are in a word, stunning. And it's a lot of fun to play a shoot-em-up that leaves the conventional retro pixelated setting and dares to take it to the farthest reaches of the universe for a truly immersive experience.

Want a solid retro arcade shooter? ASCII and you'll receive Battle for Asciion, by Relevo Video Games. Designed with a lot of love for its textual aesthetic, Battle for Asciion is a solid and challenging shoot-em-up, though hampered by its required button-mashing.

In Super Villainy, the mightiest villains have grown bored after destroying the earth, and decide to have one final battle royale, arena shooter style, to determine who is the baddest. A solid release by Rob Almighty, with a little more freedom than what is usually seen in the genre.

Theo's been working in the slave mines for years, and has finally saved up enough to buy a cruiser. Now, if he can just shoot his way through this orbiting traffic, he'll be ready to start his new life. Originally conceived by Christopher T. Rock, with later additional development by Bryson Whiteman, Rush Hour Plus is a short but solid arcade game. It's bifurcated development is apparent in the differing styles of cut-scenes and game action, but it has a nice dose of humor and is the perfect length for a coffee break.

Jonas Kyratzes has brought us many enjoyable, thoughtful games in bizarre, surreal settings. Well, now he's developed a top-down space shooter, Traitor. Don't get scared, he's still able to cast his powers of storytelling, it's just in a different yummy, gooey, science fiction package. Take on missions to earn credits for upgrades as well as the trust of the rebels. Your ultimate goal: to take down the Augustan Hegemony. Viva la People's Council!

Mission in Space: The Lost Colony is an extremely customizable turn-based strategy game with an easy-to-use interface and variety of challenges that will please players of any skill level. Plus it has a valuable lesson about the dangers of ventilation ducts. Spoiler alert: they contain aliens.

Out of this World, developed by SeethingSwarm, is a short action game centered around shifting play mechanics. The game starts as two lovers leave a fancy restaurant. They aren't named in-game, but since they look British, let's call them Ron and Hermione. Anyways, Ron and Hermione decide to go for a ride on their rocket ship, but, son of a gun, wouldn't you know it, aliens decide to kidnap the fair maiden. So its up to you Ron, with your shock of red hair, your badass longcoat, your awesome umbrella, and your shooty-blasty space gun to rescue her from the extra-terrestrial's clutches.

Raze 2 by AddisonR and Juice-Tin is the latest in a long line of action shooters with spacey-marines and/or one-word non-indicative titles. Let's count them off: Doom, Quake, Halo, Descent, Unreal, and, uh... Haze. It's surprising there are any alien-demon-zombie menaces left to battle considering how quickly we're able to deploy a near-endless supply of Master Chiefs. It's a good thing then that Raze 2 has the quality gameplay and presentation to distinguish itself from the competition.

In this turn-based match-3 battling game, adorable little creatures are locked in combat (in space!) and need you to swap gems, upgrade, and earn rubies to help defeat their opponents. The only mystery is why these cuddly astro-pets feel the need to wail on each other anyway. If snuggly little kittens can't get along with giant squids, is there hope for the rest of us?

Don't you just hate when you wake up and find out that the sun is exploding? Yeah, me too. What with the shock waves of the supernova and the imminent threat of incineration, it just about ruins your whole day. Then you have to pack up everything into the family rocket ship and blast from world to world in your solar system, and because of the ever-approaching wall of flame, there's no time for sight-seeing. All you can do is try to stay one step ahead of the heat-death. Such is the premise of Run from the Sun, by FreakyZoid. And considering the title, it's kind of ironic that it's a game you'll want to run towards as quickly as possible.

I appreciate the specificity of Space Arcade: The Game's subtitle. I was seriously worried for a couple minutes that I was going to have to deal with Space Arcade: The Hit Broadway Musical. However, as much as I crave toe-tappin' hits and elaborate choreography, I enjoy Galaga-inspired pixel shooter action even more. This appears to be music-meister Matt McFarland's debut game release, and it's so much fun that maybe he should consider quitting his day job.

Front Runner's protagonist would rather sit unaccosted on his asteroid outpost, playing his space-recorder, but all the quirky locals just won't leave him be. And as arcade games have taught us for years, such aggravation can only be answered by taking the wheel of an absurdly overarmed runabout and showing all comers what-for. It takes the vastness of space and turns it into a strange, colorful neighborhood of oddly shaped planets and goofy, irksome monsters. Empty space is rarely this lively, or this silly.

You might think that the combination of Boys' Life, the monthly Boy scouting magazine for ages 6-18, and retro-action-meister Hamumu make for an unexpected pairing. Heck, I was a cub scout and even I find it a little strange. However, I do know that when the creator of the Robot Wants series releases a pixel platformer based around a trio of differently-abilitied characters fighting their way through an alien landscape: I'm there. That game is Mad Planet, and it's got quality worthy of a merit badge.

If there's one sci-fi rank that has the highest level of awesome associated with it, it's "commander". Some of the greatest protagonists of all space-time have it appended to their name: Riker, Sisko, Adama... Keen. So it's only fitting that when puzzle-master Johnathan May chooses to surprise us with rocking a vertical-side-scrolling space shooter, that he should dub it Cosmic Commander. And let me tell you, it has a challenge more than worthy of its station.

Created by Michael Molinari and Chelsea Howe for the San Francisco 2011 48 Hour Global Game Jam, The End Of Us is a surprisingly evocative game about two meteors meeting and playing amidst the strangeness and charm of deep space. As much a piece of wordlessly lyrical interactive art as an action game, The End Of Us matches its play to an engaging soundtrack and offers a short but satisfying experience.

Shooter fans! Has this ever happened to you? You're trying to enjoy blasting the latest wave of Galaga-inspired retro-baddies, but find that the old-school chiptune music and sound effects are drowned out by the relentless sounds of mouse clicking and space-bar tapping. There has to be a better way to launch a space bullet, right? Well, Devilish Games has heard your concerns, and the result is Tag Attack: a shooter that focuses more on the aiming than the clicking, while not sacrificing the intensity of the genre.

In the futuristic world of Armor Mayhem, Loussi's new action shooter, the world has run out of energy. Thus, major corporations send teams of faceless space marines to discover a new source. And, of course, once they find a planet filled to the brink with Unobtanium, they land and immediately start blasting each other in the face with lasers... what it lacks in plot depth, it more than makes up for with enough frenetic blasting action to make Master Chief jealous.

Balls in Space is a retro-style platformer where you control a white ball determined to get from one door to the next. In your way are various evil-looking squares and other shapes. Can you stop them? Special powerups and secret levels add to the challenge. You need to run, jump, and shoot your way to victory... in... spaaaaacccceeee!

You play a plucky astro-pilot in this retro-styled action adventure game, with an ill-defined though doubtlessly heroic agenda, who keeps crash-landing onto planets with hostile, labyrinthine space bases, losing your steadfast feline companion in the process. Cat Astro Phi is a nice, short action game with retro appeal, and even players who aren't the targeted allegorical Internet Citizen will find something to appreciate.

You'll be put in the space shoes of Vincent Wake, a greenhorn to the whole inter-planetary trading thing. Luckily, you'll both have the dubious guidance of Hardgrove, a man who lives inside Vincent's eye-patch (or rather I-Patch). Black Market's gameplay is at its most basic a resource trading simulation. You can smuggle illegal items if you want, but there's always a chance your cargo might get searched as you're docking. That's the least of your worries, though. A far bigger threat are the pirates that roam the trade routes.

Ah, the cosmos. It contains the whole of everything that is, was and shall be. It is filled with the awe-inspiring beauty of the nebulae, the quasars and the familiar stars. Science cannot know how big the universe is, nor can it count the number of planets or star. Every time we get close to an exact figure, a giant space whale, dubbed Harmony Keeper, starts devouring celestial bodies. Or at least, that's what this latest action/arcade title from Mofunzone teaches us.

If you're searching for a fun and chipper exploration game to kill a little time with, good for you! Searching is one of the key components of exploration games, so you're already off to a good start. After that, the fun is in what you do with what you find. In Little Rocket, you get to explore a small universe AND solve puzzles along the way! Aren't two-for-one bonuses lovely?

Got a hankering for some exploration? Cluster Lander is an exploration game and workout for your reflexes that lets you wander through mysterious terrain, fighting turrets and finding keys, all in the hopes of picking up the coordinates that will let you continue your quest to explore the galaxy!

From Nitrome comes a game about space, stars, and making aliens blow up. Guide a fledgling star across thirty levels requiring a steady hand and quick reflexes. While the control scheme may take some getting used to, Nebula is a cute, quick little game that would be at home in any arcade, thirsty for your quarters. And remember, kids. Friends don't let friends play with space bombs.

Someone in Station 38 needs your help, and you'll never guess who it is! Pat Kemp's Station 38 puts you at the helm of a lander-type spacecraft, thrusting and sputtering its way through 38 levels in response to an SOS from deep within. And when you receive a distress call from Station 38 in deep space, well, you've just gotta answer it!

Someone in Station 38 needs your help, and you'll never guess who it is! Pat Kemp's Station 38 puts you at the helm of a lander-type spacecraft, thrusting and sputtering its way through 38 levels in response to an SOS from deep within. And when you receive a distress call from Station 38 in deep space, well, you've just gotta answer it!

To boldly go where no one-eyed, rocket-propelled cat has gone before, Rockitty needs your help in this bouncy, bizarre arcade space adventure from Nitrome! Explore the milky way, battle dangerous space squid, collect delicious fish, and more across 22 levels of space cat fun. It's a wondrously weird, frequently squishy game that plays like pinball. In space. With one-eyed green cats. Just as Mother Nature always intended.

Gravitee 2 is space golf! In space! Send a ball out into the cosmos, whipping around planets and barreling through hoops. With 90 achievements, 4 different medals awarded per level, rewards to unlock, and a well-crafted level editor, you'll want to put your space pants on, grab your space mouse, fire up your space computer, and spend some serious time playing space golf.

We wanted a harder game with a stronger story, and that's what developer David Scott has given us. This sequel/mission pack to The Space Game offers a larger variety of missions, spread across three sub-plots that have you protecting valuable military hardware or facing never-before-seen threats from the pirate army. The tight, balanced gameplay is the same; it's just more engaging this time.

In this tribute to vector arcade classics, you must make it through 10 levels containing deluge after deluge of asteroids without letting them knock you all the way to the bottom of the screen. Crash into as many asteroids as possible for bonus points!

A game of pure reflex, Zodiac Reactor blasts spiraling orbs at the center of the screen and asks you to collect them with near-perfect timing. It's like an intense bout of hyperspace Simon. If you are skilled enough, your reward will be the creation of a brand new star of your very own!

Reach for the stars — literally — in Casual Space, where treasure, danger, and secrets are sprawled across two enormous maps comprising over 40 levels of spacey action! Balancing a quirky, kid-friendly presentation with some genuinely challenging gameplay, Casual Space is good casual fun for all ages.

Starcom is a top-down space shooter and strategy game, with subtle RPG elements like a well-paced story progression and "missions." You are stationed aboard a Galactic Command Starbase (space station), playing the role of a space fighter pilot with a starting mission of fending off alien attacks. Starcom really shines, revealing story elements at just the right moments while incorporating it all into the gameplay progression.

Defend yourself against waves of foes in space, where a click of the mouse unleashes massive explosions to decimate enemy fighters, because making peace is overrated when you have a limitless supply of missiles at your fingertips.

So what if you have nerves of glass, a strong pull towards buttons marked 'DO NOT TOUCH' and a crippling fear of heights? Azul Baronis needs you to lead a squadron of spaceships against ever-increasing odds in this fast-paced intergalactic shooter. Buckle up, Commander.

Moon Rocks is an impressive little shooter-defense game that's pretty challenging and fun. Loosely inspired by the classic arcade game Missile Command, you defend your little chunk of the planet's surface from an onslaught of asteroids, ice comets, enemy ships and plenty of other things that threaten to turn your base into Swiss cheese.

Orbital Decay pays homage to the Super Nintendo era of 16-bit graphics by incorporating some really cool and interesting strategy elements into the formula of a classic side-scrolling shooter. As the commander of a massive battleship, you must upgrade various weapons and fire your main cannon (the Ultragun!) to defend yourself against waves of crazy-looking alien ships.

In ooPixel's brilliant new action game Escape the Red Giant, the sun is about to die, and you have to keep yourself alive for as long as possible by jumping from one asteroid to the next. Between the detailed physics engine and the tight gameplay, you may find yourself addicted without realizing it.

The latest real-time strategy game from tower defense master David Scott sets you in deep space, defending your asteroid mining operation from humongous swarms of space pirates. The freedom of building in two dimensions gives you a lot of room to experiment and find your own strategy, and the sheer scope of the massive battles make it feel like quality space opera. Constant tension plus simple controls plus nearly unlimited mathematical depth equals awesome strategy game.

Smooth and bold, with a delicate, classical presentation and a spicy but brief aftertaste, Space Pips serves as a nice pre-dinner aperatif for those with a taste for Geometry Wars-style arena shooters.

Monolist, from Japanese developer (or possibly super-powered spy team) Polygon Gmen, is what you would get if you took classic Space Invaders gameplay, multiplied it by three, strained it through a net made of Arkanoid bonus drops, and then sprinkled in nine hundred million bullets. Like a recreational energy drink, it's cool, refreshing, burning sweet, and highly caffeinated.

Space Kitteh is a unique action game created by Zach Archer and Miles Johnson for our fourth Casual Gameplay Design Competition. Run around planets bouncing around in space as you search for lost kittens in distress. As you leap about, gravity toys with your momentum in strange ways. It's a great-looking game with just enough wackiness (saving kitties from planets?) to make it a winner.

Space Pilot, by Alex Kaplan, is the spiritual successor to Asteroids, featuring the same vector-style graphics, the same ship, the same control scheme, and even the same asteroids. I was really tired of Asteroids itself decades ago, but picking this game up feels like I'm putting on a pair of old familiar boots and going for a stroll in a brand new town.

Benjamin Colwell of Indie Flash Arcade has just released this remarkably attractive arcade Flash game that blends the casual gameplay of classic video games with a stylish (and stunning!) presentation. The result is POD: Planetary Orbital Defense, a 15-level shoot-em-up bonanza that culminates in a boss fight against an alien invasion.

Gamma Bros. is a deliciously slow-paced old-school space shooter created by PixelJam. It's written in flash and offers both an online version and downloadable files for the Mac and Windows. Although simple in looks and design, Gamma Bros. gives the illusion of a massive game world interspersed with moments of action and quiet space floating.

Another one for the classic games section, I made a reference to this game when reviewing Swarm due to the way the enemies swarmed onto the play field. Galaca is a Java applet 'clone' of the classic action arcade game Galaga. Originally created by Namco and released as a coin-op amusement...

Raiden X is an excellent Flash shooter game that is a lot of fun to play, though it was a bit easy for me to complete on Normal difficulty. The trick is in the power-ups, which are many. Tons of enemies and larger boss-types in this game. Excellent Flash work by a talented, young (age 13!) game developer.

Arguably one of the greatest video games of all time, and certainly one of the classics, Asteroids was released to the arcades by Atari in 1979. Twenty-five years later the game is still captivating gamers with its gameplay and its physics. But Belter is better. From creator Russ Duckworth's Truantduck Games comes...

A game that looks and feels very similar to Nintendo's Starfox games, Starfish Chronicles is a Shockwave game of the same space-flight shmup genre. The game makes effective use of many of Shockwave 3D's more advanced features to create a compelling experience that rivals commerical offerings. Although control is with the arrow keys and the space ba...

This well-crafted Flash game is a simple shmup that is fast and furious, as well as addictive. He's done a nice job with implementing power-ups, bonus multipliers, smooth animation particle effects, and a high score list, too. So, if you like shmups, you're gonna love SpaceFighta.

A fantastic Asteroids recreation from Shawn at Hot Flash Games, and boy does it rock! Very authentic classic gameplay with a serious modern soundtrack that just... ROCKS! Shawn did an excellent job designing the sound for the game, as it contains a mix of classic Asteroids samples and some phat rocking beats.

Back in the day, Space Invaders, by Japanese company Taito, was one of the coolest games to come along as it was one of the first (if not the first) electronic game ever to offer open-ended gameplay. What that means is that it's impossible to 'beat' the game, the aliens just keep coming at you relentlessly.
