This game is rated ESRB: Everyone for Mild Fantasy Violence.
Kokuga is a top-down mech shooter developed by G.rev, released for Nintendo 3DS in 2013. Players pilot a mech across grid-based stages, navigating enemy fire and progressing by defeating each level's boss. The game employs a polarity system in which enemy projectiles come in two colors, and survival depends on switching to the corresponding color to avoid damage — a mechanic reminiscent of G.rev's earlier work on Ikaruga. Stages are structured around deliberate, methodical movement through the grid rather than constant high-speed action, giving the game a measured pace compared to traditional shooters. A cooperative multiplayer mode is also supported, allowing multiple players to tackle the game's challenges together. The combination of color-switching mechanics and grid-based level design distinguishes Kokuga within the shooter genre.
