ALIENWARE has just released AlienTetris, a mod for the game HACKAH with an alien them. In this Tetris-like game, you play as a hacker that must compete against the alien's most advanced computer system. Essentially, the goal of this game is to complete enough rows of blocks to make it to the next level by filling the red meter up all the way. Best of all, this game supports custom music if you can convert your .mp3 files into the .wav format.
Overall this game isn't a whole lot different from Tetris, but the cool alien theme is worth trying out!
