Tripwire Interactive has announced that the retail version of Zeno Clash is now available. The press release notes that the game is available at Best Buy, and a quick search reveals the game is available from several other sources, including Newegg and Amazon. The retail version includes Steam Achievements, the full single-player campaign, survival mode and free extra content known as "The Pit." For those unfamiliar with the game, it's a first-person adventure in which you beat up lots of weird-looking dudes in a bizarre fantasy world. If that doesn't help, we've handily embedded a trailer for the upcoming XBLA version after the break.

Zeno Clash has landed some decent reviews since it launched, so those of you who held out on the downloadable release might consider picking up the $20 retail package.
