If you are looking for a game to play, Totem Arts has released their fourth public beta for Renegade X. You have probably heard of the game by now but, if not, it is a third-person shooter that is in the style of Command & Conquer: Renegade. Each team has a base that provides weapons, vehicles, and upgrades in exchange for credits. Players then use this superiority to destroy each others bases (and each other directly of course).
The game is powered by Unreal Engine 3 through the UDK program. From what I can tell, they are using the February 2014 build, which is a little over a year old but relatively up-to-date technologically. Epic Games added most DirectX 11 functionality back in the March 2011 UDK beta release. It looks quite good too.
And it's free (not free-to-play). Check it out.
