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.

Daymare Invaders, an arcade shooter, isn't a particularly complicated game. Essentially, it's Space Invaders with a Daymare skin. But you know what? The hand-drawn art of the Daymare world is as hauntingly beautiful as it was when we first saw it. If you go in expecting anything more than a clone, you'll be disappointed. If, however, you approach it knowing what it is (a classic minigame and a tantalizing preview of installments to come), you'll find a very tasty piece of eye candy.

Space Invaders, Missile Command and Breakout are like the venerable elder statesmen of the video gaming world. But what if hundreds or thousands of years in the future, scientists are picking through a then-ancient landfill of Atari 2600 cartridges and have to try to piece together what they mean? They might come up with something very much like the arcade mash-up Missilebreak Outvaders. A classic example where the whole is greater than the sum of its parts, with three classic arcade games rolled up into one awesome experience that is exceptionally fun to play.

Two years ago, Antony Lavelle released Upgrade Complete. A mix of shoot em up and space invaders, the games main purpose was to unsubtly parody one of the more obnoxious aspects of modern gaming: the inclusion of unnecessary and convoluted upgrade systems. Everything came at a price and had to be bought: weapons, graphics, music, buttons... even the pre-loader and Armor Games intro animation. However... it turns out that the developers weren't quite done... After all, what is an upgrade system without a sequel that requires you to restart your progress from the beginning? Thus comes Upgrade Completer, a game that advances the original's premise as much as its humor.

Pong and Space Invaders are two of the most beloved old-school arcade games of all time. Ikaruga and Portal both often make the short-list of modern classics. So what do you get when you combine Pong's bouncing, Space Invader's baddies, Ikaruga's polarity shifts, and a decent dose of Portal's plotting? ReflexION by FreeSparkGames. And while it might not be included in the gaming hall of fame like its inspirations, it's a more than worthy way to pass an afternoon.

Panic is a simple and stylish arcade game made in homage to a classic on the Commodore 64, Astro Panic. Made in Flash and sporting an impressive new soundtrack as well as eye-pleasing particle effects, Panic plays like a cross between Space Invaders and Pang.
