Independent game studio
We make games we want to play with our friends: deep progression, co-op at the core, and online worlds we build and run ourselves.
Our games
3D Fantasy Tower Defense · Action RPG
Coming to Steam October 27, 2026
The moon bled, the rifts tore open, and the Cinder King's legions are still pouring through. Build the maze, level your towers by standing on them, and hold the rifts solo or in 4-player online co-op.

The studio
MagmaBear Games LLC is a small independent studio that develops and publishes its own games. We write the game, the servers behind it and the tools around it, so the people making the game are the same people keeping it running.
Our first release, Eternal Rift Defense, is a 3D tower defense action RPG with online co-op and ranked PvP, coming to Steam on October 27, 2026.
