G.Rev is developing a new shooter for 3DS. Titled Kokuga, the game is revealed in Famitsu this week to be a tank-based overhead shooter that's playable simultaneously by up to four players, complete with support for download play.

The game's stages are placed on a grid of triangles. You're free to select your starting stage. When you clear a stage, you unlock the three neighboring stages.

Kokuga will be released in Spring 2012. Development is currently at 40%.
