CryEngine based arena shooter Nexuiz launched earlier this year on console to mixed reception. Now it's available on PC, and could be worth a serious look due to various enhancements.
So, here's what you get: dedicated servers and server browser, better graphics with DirectX 11 features, customs controls, a new HUD, and a 20% increase to speed so it's more twitchy than ever. Dedicated servers at least don't appear to be in yet, so you may have to wait on the other enhancements, as well.
In any case, the game is on Steam and various other digital shops now for 10 bucks if you're interested.
