It’s likely that you haven’t heard of Battle Splash. The game is a non-violent, online multiplayer-focused FPS in which anime-styled girls shoot each other with water guns. It’s largely the same as many other FPSes, featuring pistols, rifles, rocket launchers, and so on, only players sit down when they’ve been hit rather than dying.
The game’s Pre-Alpha version has been available for some time now, but it was only playable over LAN. Last week, however, the first Alpha version was released, finally introducing online multiplayer. The patch that introduced multiplayer also introduced a new map, Medieval Citadel, and enhanced motion blur.
Those who are interested in trying out the Alpha version can download it here.
