Contra fans will really enjoy this new chapter for mobile. This is not some bastardized version of the game, shoved on to handsets to help market the DS game. This game was built with mobile in mind, such as the pacing of the enemies, and succeeds because it respects the limitations of the platform. Casual gamers will tear their hair out over the game's difficulty, but fans certainly know to expect this and will love the game for it. Give it a download. And then move away from crowded areas, because you will say some unsavory things.
