Got a hot cellphone that can run Java or BREW apps? Then you know you need DoomRPG, a turn-based role playing version of the popular Doom series. It looks extremely well done and is designed to play like everyone's favorite favorite FPS. You can get UAC credits and buy ammo and health, interact with scientists, and level up your character. No multiplayer, which sucks, but with all the features DoomRPG has to offer I'll let them slide this once. The coolest aspect by far is all the new enemies, each with it's own class and 3 different strengths. If you demand mobile fragging with a twist, you need this.
