Zeno Clash: Ultimate Edition

In the land of Zenozoik, the city of Halstedom is ruled by a powerful clan, one  which Ghat has betrayed by committing a terrible sin.  Now, Ghat's brothers and  sisters are pursuing him and his companion Deadra through strange and twisted lands, beyond the boundaries of the sane to the ends of the world.  What was Ghat's crime and why did he commit it?  The bare-knuckled brawl to reach the truth has just begun.
Key Features

* Fascinating world of grotesque beauty–Equal parts breathtakingly beautiful and utterly disturbing, prepare to be swallowed up in a surreal fantasy world powered by the Source engine.  Explore lush environments and confront bizarre animal-humanoid foes on your mission of discovery and redemption.

* Visceral first person fighting–Combat is up close, personal, and entirely satisfying. Start with a series of punches, kicks, and grabs, follow up with a knee to the enemy's face, and hit him with a finishing move to send him flying yards away. Learn new moves to mix it up. Guns and melee weapons offer additional power and tactical  options.

* Ultimate edition additions–The already highly praised gameplay has received an overhaul that includes combat rebalancing, interface enhancements, improved animations, new modes, and new gameplay content.

* New cooperative play modes–Enlist a friend to take on enemy waves in Tower Challenge, a special survival mode that offers additional replayability beyond the single-player campaign.  Play cooperatively online, or locally via split screen.  With leaderboards to rank you against your friends, the challenge never ends!
