Tripwire Interactive made the decision to publish their monster co-op themed shooter Killing Floor to retail stores themselves. Now the small company is expanding its retail publishing arm by handling the US retail release of Zeno Clash, the very original first person action game from developer ACE Team.

Previously available only as a digital download title, Zeno Clash will soon be made available as a boxed retail game to stores in the US and Canada "soon" according to Tripwire's press release. The retail version will contain the original single player campaign, the eight challenge maps that were released later as a free download and the optional model pack that can be used in Garry's Mod.
