Several mobile gaming companies are developing cross-platform multiplayer games allowing Android and iPhone users, for example, to play games against each other. Last month touchArcade reported on a cross-platform baseball game developed by Com2Us called Homerun Battle 3D. Unlike turn-based multiplayer mobile games, Homerun Battle 3D allows players to compete against each other instantly, but you don't see the other player — instead you only get to see your competitor's score being updated. Pushing cross-platform multiplayer games even further, a company called Bulky Pix has created a table-football-style game that displays the action as it happens — both players see the ball moving around. This hopefully suggests that cross-platform, multiplayer mobile shooters aren't far behind.
