Man, what a JOY this game is once you figure it out and start playing the right way, get some builds going, and melt bosses.
It's resource management done right.

Also the OST is really damn good, I sometimes pause the game just to headbang to it.

The biomes are all great, my favorite is the third one, Interport, because of the atmosphere and enemies.

If you like FPS games or Roguelikes, do NOT miss this game.
