Undersphere

Sounded confusing. It wasn't. You're inside a ball, up is wherever you happen to be standing, and after a minute your brain just accepts it. Good late one

Gravity pointing outward rewrites every engagement. What I'd want to watch is the camera when your up vector rotates, because that's where movement shooters go to die. Lobbing something across the interior and having it arrive under real gravity is a proper hook rather than a gimmick: it turns throwing into a decision instead of a panic button.

Living on the inside of a sphere counts as a setting, not just a level. The horizon curves up towards you instead of falling away, and that reorders your sense of place in a way no flat arena has managed on me. Best part: a fight ends up with a shape you can read from anywhere in the world. Rarer than it sounds, that.

Does new geometry ever bring anything but new confusion? Usually not. My honest worry going in was nausea, plus a map nobody could hold in their head, and it mostly gets away with both because the movement stays conventional under all the weirdness. Right instinct. It's still an arena shooter that needs bodies in it, but the idea earns the click.

so the floor is everywhere, you're running round the inside of a ball, and it is a fun stupid feeling. Took me a while to stop trying to look up. Do keep in mind it's a shooter that really wants other people in it. Poke at it when your brain is off and you will have a good time.
