Geometry Wars: Retro Evolved is one of the best-selling games on Xbox Live Arcade. It was a good move on the part of Sony BMG to bring it to a platform which can easily be accessed by people on the go. Geometry Wars: Retro Evolved Mobile, which is still in development, maintains the flashy graphics as well as the frantic gameplay that players came to enjoy since the Xbox Live version debuted in 2005.

Speaking of gameplay, Bizarre Creations added extra challenge modes to test your keypad-mashing skills.

Evolved Mobile Mode. Identical with the XBLA version, foes appear as your multiplier increases. The gameplay becomes hectic when even more enemies spawn left and right. If you're lucky enough to get a high score, it will be posted on a network leader board and local ranking table.

Immortal Mode. This is the mode for the first-time GW players. Think of it as a practice mode where you are invincible. There are no scores and multipliers, but you can still view bomb and life meters.

Challenge Modes. This is similar to the Evolved Mobile mode, but there's a pre-defined objective to achieve. The objectives under Challenge modes are: Untouchable, Survivor, Monster, Trenches, Speed, Multiplier, Feline, and Bomber. Among these, the most challenging would be Untouchable, wherein you make the most of your "one" life with no weapons or bombs. It's basically testing how long you can hold out just by dodging.
