"Xeno Clash" was one of those games i picked up on the Xbox 360 market place a while back and eventually found on Steam later. I very rarely hear anyone talk about it so I'm just gonna assume that its fairly obscure.
I remember it looking good for a source engine game, particularly since it used entirely original assets in conjunction with an art design that made it look like a Hieronymus Bosch painting. Weird doesn't quite cut it as a description; while the game has a pretty sweet combat system (at least from what i remember) it was weird to a point in which playing it would often give me headaches or a slightly nauseous feeling...so...yeah. Its sequel is pretty good too.
