Jussi and Marko, Flash game developers at ooPixel, borrow a little gameplay from several classics and wrap them all together into one nicely polished and addictive game. Asteroid Adventure is an arcade action game that will be both familiar and new to anyone that has played Asteroids before.
Control is with the arrow keys for direction and movement, press [space] to shoot. It's as simple as that. Your health meter is shown in the lower left corner of the game window. It is reduced for as long as you come in contact with an enemy, so move away quickly if one comes close.
The first level is classic Asteroids with a few added features thrown in for good measure. Health meters appear on enemies that require more than a single hit to take out. Power-ups sometimes appear (after eliminating an enemy) that can boost health, gun power, gun rate, or shields (invisibility). The power-ups are few, however, and this makes the game quite challenging.
Level two (shown) introduces new enemies that move as in the classic game of snake, which gives the game a fresh new feel. Later levels introduce even different enemies, with the difficulty ramping up very quickly.
All things considered, Asteroids Adventure is a well-produced game that takes classic game ideas and creates a unique and original new game from them.
