ACE Team have promised they’ll be releasing the SDK for Zeno Clash since release, and because they’re honest folk, now they have. The Source-based first-person thwacker is one of our favourite games of the year, and you’d have to be Earth’s Wrongest Idiot not to find the game’s world fascinating and beautiful. Now using the magic cogs and accompanying text files, you can create your own levels and mods for the game. That link will guide you toward the SDK itself, as well as all the accompanying documentation. If you make something excellent, make sure to let us know.
