Screencheat

Smooth and fluid little split screen multiplayer FPS, with a hilarious variety of weapons and of course, the primary quirk of the game alluded to in the title: You aren't able to see your opponents, gaining clues to their location from seeing their viewpoints and occasionaly from 'tells' that their weapons give.

I find that the sound effects suit SC well enough, with standard weapons sounding the way you'd expect.

I remember watching YouTube videos of Screencheat (SC) and found it to be a fascinating idea for a multiplayer FPS.

Further props are deserved for the level of customizability with the ability to unlock various silly skins, editing level mechanics such as gravity and movement speed, mutators that alter the gameplay in various ways, the options are quite fast.

TL;DR This is a fun FPS with a neat gimmick and both local and online multiplayer support, so as long as you've willing to try and learn the gimmick and you've got some friends to play with, I'd recommend picking this one up.

Visually, Screencheat embraces a bright and abstract art style that perfectly complements its gameplay.
