Zeno Clash (PC)

This is a very unusual game with strange, surreal visuals, and a confusing story, yet it's also strangely interesting.  Zeno Clash is filled with odd-looking creatures, and a pre-industrial punk-like sensibility.  It's a first person action game where you spend a lot of your time punching and kicking enemies, though there are still times where you can use firearms.  The game is very short (only 4-ish hours), but it certainly is an experience.
