I can forgive you if you haven’t heard of Killing Floor before today. You see, while it has previously enjoyed a strong following in the niche market of mods, it was only recently brought to the attention of some big names in the PC gaming industry; that being Valve, of course. The gist of it is: small team of four releases mod for Unreal Tournament 2004 back in 2005.
The mod is popular and gains a devoted fanbase, and the mod continues to improve, expand and grow until it reaches version 2.5 in 2008, at which point the guys behind it grab the attention of a company by the name of Tripwire Interactive, who strike a deal with the mod team and Valve to release the mod as a standalone game via Steam.
