Vector Conflict: The Siege takes you back to the early days of arcade games, back when games like Tempest and Omega Race were the new guys on the block. With its glorious vector graphics, Vector Conflict looks like the brother of the classic tank combat game Battlezone, and plays like a cross between that and a turret defense game.

Man-eating plants! Skeletons! Giant spiders! Falling boulders! What do these things have in common? They're all very, very deadly.

Explore, descend, discover... just remember to watch your back and keep one hand on your whip!

Zamby and the Mystical Crystals is a top-down puzzle adventure game with a lot of retro charm. Similar to the Wonderland Adventures and Professor Fizzwizzle series in concept, its simple visuals hide a box-pushing puzzle game with a surprising amount of challenge and content. It also takes itself serious as a casual game, offering a full, move-by-move undo option along with hints and full solutions for every level. It's old school gaming without the old school headaches!

Bleep, bloop, assimilate! The life of a robot is hard. When you're slated for that big old junk heap in the sky, do you go quietly into that long good night? If you're playing Mechanaughts, a quirky little action platformer, you fight your way to your oppressors and take your mechanical revenge. Since robots tend to have cold, unfeeling metal pincers for hands, that revenge is unlikely to consist of hugs and a heartfelt discussion on your feelings.

Your journey as Arkus Rei, space pirate, continues in this series of extremely challenging platform adventures. Follow the instructions given by your new found human companion to uncover treasure beyond your imagination. But first you must travel to several different dangerous locales and, well, survive.

Frantic 2 is as calming as a warm, lilac scented bubble-bath on a late summer night. Assuming your idea of calming is a screen filled with dozens and dozens of enemies, projectiles, power-ups, and laser fire. With three big levels, five modes of difficulty, upgrades, and more, Frantic 2 is prime scrolling shooter action for the twitch gamer in all of us.

The first Flash game from Anna Anthropy, When Pigs Fly is an extra-challenging offbeat platformer about a pig who has to escape from a cavern using her newly-grown wings, which are unfortunately the most fragile creation in the history of the universe. Even negotiating a simple floating block takes some skill, and an innocent staircase becomes a jagged nightmare.

Cheerio, my good man, pip pip! The name is Sir Reginald MoneySeize II, Esq. I'm out to construct the world's largest tower, and I'll need 1000 golden coins to do it. Are you up to the platform-jumping challenge, my well-buttered scone? I sincerely hope so, for I'm simply too well bred and important to fall to my death on a bed of spikes.

Deadly Sin doesn't try to reinvent the role playing game. Instead, it chooses the path of flattering imitation.

Hack and slash your way across the ancient land alone or with a friend in this gorgeously quirky side-scroller from Nitrome. When your sword fails you, don't despair — a nearby boar will do just as well. Or a chicken. Rendered in Nitrome's familiar pixel-perfect art style, Double Edged not only looks great, it plays great too.

When you load up Raider: Episode 1 in your browser you can expect solid controls, a good story, and magnificent level design that will put your platforming skills to the test. This first in a series of five episodes sets a high standard for the four episodes to follow.

"Avernum" is the name of an underground domain that's home to the Avernites, a group at war with the surface-dwellers, collectively called the Empire. This time around, a group of adventurers is sent back to Avernum to hunt down an assassin who tried to kill the Empress. The story and its development is actually pretty thick for a closed-in dungeon crawler, unfolding constantly a simplified "choose-your-own-adventure"-styled dialogue.

Action, adventure, and painful, spiky death can all be yours in Chup, a new platformer from Tomas Pettersson. With a retro vibe and an intensely charismatic star, Chup offers a tricky jumping adventure that would make Mario proud.

The Tales of Bingwood Chapter 1: To Save a Princess is a 2D point and click adventure that is a throwback to every Sierra and LucasArts game ever made. Maybe not every single one, but most of them. The ones that were made in the '80s in which the main character went on some sort of quest and had to click on everything and try to combine all the items in the inventory with all of the other items and where do they even get pants with pockets that big?

Building upon the classic franchise released over two decades ago, Defender of the Crown: Heroes Live Forever is an excellent successor to the original game. It keeps intact many of the important things from the original game, including the minigames, much of the strategy of the main game, and the beautiful graphics, while giving the game an update that helps to bring it into the modern realm of casual gaming.

The Malstrums Mansion is a retro point-and-click game with a surprisingly tense atmosphere, in the style of old Apple Macintosh adventures like Shadowgate. The heavily pixilated black and white graphics are chunky but lovingly crafted. If you love games that give you the creeps, or if you just like to relive the early years of gaming, this is a title you simply can't afford to pass up.

Double Fine president Tim Schafer is hosting at this years Game Developers Conference, and he's totally unprepared.

If you have even the slightest nostalgia for early graphic adventure games such as The Secret of Monkey Island, then this sharp, clever point and click adventure is made for you.

Don't Look Back is a modern retelling of the story of Orpheus and Eurydice, although there are subtle differences. For one, the mythical greek poet favored a harp over a handgun, and for another, he didn't need your platforming skills to guide him on his journey.

A new addition to the Wonderland series, retro-themed isometric puzzle/adventure games that are of the best around. They retain the spirit of what makes the genre so enjoyable while adding new, more modern twists to the experience.

A rhythm-based Wario Ware type of game from Nitrome, in which you play colorful mini-game levels with a musical timing element. Destroy attacking fighters and tanks as Godzilla! Stake vampires as they rise in their coffins! Um...eat...stuff. It's all here, with three difficulty levels across four distinct stages, a different song in each level, and a final "mix-tape" stage that surreally switches context between the stages over the course of the song.

Andrew the Droid is a retro-looking title that utilizes the familiar level rotation concept found in a number of games. Work your way through over two dozen levels, avoiding hazards as you unlock exits, collect chips to grant you new abilities, and rotate the stage to let gravity pull you where you need to go.

A short and sweet old-fashioned adventure game from Videlectrix, the faux video game company of the animated Homestar Runner universe. For the Homestar un-hip, "Dangeresque" is the hard-boiled detective alter-ego of Strong Bad, who is the lead narrator and practical jokester at homestarrunner.com. Strong Bad/Dangeresque must solve a murder case from the confines of his office, because the chief thinks the case was solved months ago.

Out of Order is a humor-oriented, mouse-driven adventure game in the style of the old Lucas Arts and Sierra titles. You play as Hurford Schlitzting, an ordinary human being in a green bathrobe and bunny slippers. Late one night he's awakened by a storm and goes to get a midnight snack. And then the game ends... wait, no, it doesn't, or we wouldn't have much of a game.

Ben There, Dan That! is an old school adventure game in the classic sense. You know how this works. Right click to access the interactive menu. Interact with objects. Pick them up. Use them with other objects. In this game, you default to playing as Ben, but you can switch to being Dan when the occasion calls for it. It features some fairly witty writing with that rather unique British self-deprecating sense of humour.

What happens when a game's mechanics are affected by, well, themselves? That's what Mark Essen of Messhof Games might have been wondering when he devised the idea for Flywrench, a downloadable freeware game in which you must guide your bat-like ship through a maze of obstacles to the exit.

Think of the classic Space Invaders mixed with a dash of Galaga and you'd have a pretty good understanding of what Titan Attacks! is all about. The classic "aliens descending from above" scenario is showcased with a stylish, blocky pixel motif featuring a richer move-and-shoot routine than classic predecessors. Titan Attacks! took the golden age concept and loaded it with a variety of new action elements and ship upgrades.

In Ginormo Sword, you play a pink, ninja-looking hero equipped with a sword that you must upgrade, making it bigger, longer and more powerful. A fantasy action game with subtle RPG elements drawn from the golden age of Atari and Intellivision games, packs a satisfying punch for such a pixelated style, like most other games from Japanese designer Babarageo.

Wonderland Secret Worlds is an isometric puzzle adventure similar to Mr. Robot. Take control of several characters who push boxes, flip switches, roll boulders and build bridges to make it to the exit in each stage. The setup is nothing new in casual gameplay, but somehow the combined package is an extraordinarily fun play. If you don't mind the dated visuals and rather cutesy presentation, Wonderland Secret Worlds will be one of the most enjoyable and satisfying games of its genre you'll ever dive into.

If something considered "retro" gets remade, is it still considered retro? Such is the question to ponder while playing Arcadia Remix, the juiced-up retro remake of Gamelab's multitasking classic, Arcadia. This newer version adds to the retro insanity with more mini-games and gameplay features to make your head explode in a neon rainbow.

The fine folks at Pixeljam have really managed to outdo themselves this time, bringing us an outlandishly retro, high stakes, mad multiplayer dash for survival called Dino Run. Although there are three modes of play, the idea is basically the same: run as fast as you can!

If "retro" to you means huge chunky pixels, bleeping and blerping sounds and gameplay that doesn't lead you by the hand, then Attack of the Meeplings may be just the game for you. This Java-based shooter is glorious, retro-styled fun from top to bottom, especially its soundtrack.

Thule Trail is a re-imagining of the grade school classic, Oregon Trail, but instead of playing a family of 19th century immigrants, you play a group of 20 somethings road-tripping to a music festival. Instead of going to Oregon, you're going to Santa Barbara. The game takes its name from the 20th century occult society that sought the road to Atlantis; the music festival you travel to is called Atlantis, so it works. The rest of the game follows suit like a friendly slacker.

Hearken back to those adrenaline-happy days with Vector Runner, an arcade action game concerned purely with the sensation of speed. Control a humble blue cube on its journey down a futuristic highway, dodging deadly pyramids of various shapes and sizes. Wherever you need to be, you're going there fast.

Pile O'Bubbles is a new action/puzzle game from the creator of Gravity Pods, Keith Peters of Wicked Pissah Games. It combines fast reflex mouse clicking with a bit of thinking to create a game that's brain wrenching with a touch of (very) old school arcade style as well.

Gravity Pods is a physics-based vector shooting/puzzle title created by Wicked Pissah Games. The goal is to fire a projectile and hit a target across the screen. Barriers are usually in the way, but by using gravity pods you can bend the path your projectile takes to send it virtually anywhere on the screen.

In Rat Maze 2, you are a mouse in a maze and you must collect all the pieces of cheese in the shortest time possible. Use the arrow keys for movement to zip around the maze. Running over a cheese is as good as eating it, so no time is wasted collecting them all. Simple retro fun from the highly talented developers at PixelJam.

Sunday Lawn, a game from the creator of Castle Smasher, Donut Games, puts you in control of Charlie whose job is to cut the grass around his house. Unfortunately there are dogs, hedgehogs, and various other obstacles standing in the way of monocotyledonous perfection.

Dot Action 2 is a cute little platformer with a personality. For those seeking some old-school gameplay, OffGao of Japan may have just what you're looking for. At first glance these games may appear as nothing special, but as was the case with many early video games, it's all about the gameplay.

In Flatland, it is your mission to destroy wave after wave of... things. You get points. OK, the idea isn't completely original, but the design is quite interesting. At first you start off in a tiny ship with litle armor and a miniscule weapon. Destroying enemies will cause them to explode in an array of large blocky pixels, the collection of which upgrades your ship. The interesting bit is that collecting an odd number of them gives you an odd shaped ship until you gather more and regain composure.

Snake Classic takes this simple game mechanic and gives it new life with catchy music, tons of gameplay options (how many dots to grab, sound effects, etc.) In addition you get to choose what colors your snakey protagonist will have using a grid of dots that looks like something out of a kid's dream box of marbles.

Skatefall is John Freeborn's tribute to one of the earliest platformers, the Atari 2600's Pitfall! With a bodacious new skateboard, online scoreboard, bonus items and powerups, 2D platforming has a new name: Skatefall Harry. As a homage, Skatefall is extremely effective and faithful; the graphics and sound are perfect and the difficulty, while formidable, is appropriate.

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 PC. 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.

Rainbow Wars is a retro-style arcade shooter available as a free download for Windows, and it is one of those rare finds that becomes an instant favorite once you see it in action. Sporting similar controls to that of the classic Robotron, in which two joysticks are used to control movement and firing separately, this game captures the essence of a classic arcade experience in a well-developed albeit small package.

Thy Dungeonman 3: Behold Thy Graphics! is a parody of the old 5¼-inch floppy text and graphic adventure games. Made by Videlectrix, Homestar Runner's fictional software design company, Dungeonman 3 sports "state-of-the-art amber monochrome visuals" (circa 1980), real-time simulated medieval English text, a parser that talks back to you, and enough mocked adventure game cliches to fill your beer stein twice full.
