The History of Killing Floor

Killing Floor started life as a mod for Epic’s Unreal Tournament 2004. The mod was first released in 2005 and has steadily grown in popularity. It was featured in PC Gamer and PC Zone magazines back in 2005, plus various sites across the web. A small core team, led by Alex Quick, kept the mod going. As with all mod teams, people came – and people went. School, work, life and being eaten by stray specimens all took their toll on the team. By 2008, the mod was up to version 2.5 and a small but dedicated and perfectly-formed crew of 4 people.

During 2008, Tripwire was the first company outside Valve themselves to put out mods to their games over Steam, with the release of “Mare Nostrum” for Red Orchestra: Ostfront 41-45. Given Tripwire’s famous background as a mod team, this was no surprise.

Later in 2008, Alex brought Killing Floor to Tripwire’s attention, with a view to moving it on to Red Orchestra and lining up a mod release over Steam. We took a look and decided it was way better than that. So, a deal was done, Tripwire bought the rights to Killing Floor, took on the mod team and set about prepping the game for a full retail release over Steam. Valve, as always, were hugely supportive and all that was required was an insane level of effort from Alex, Myles, Marco and Zynthetic from the mod team, plus more insane effort from the Tripwire crew.

Killing Floor was announced to the world through IGN and Voodoo Extreme and a new article in PC Gamer UK. The response was excellent. To quote: “you can never have too many good zombie games…”. And the rest is down to YOU!
