Orc genocide is never pretty, so you should probably sample it before you decide if Orcs Must Die! is for you.
That’s exactly what you can do on the PC (via Steam), as a demo and early purchase offer for Robot Entertainment’s tower defense-ish greenskin slaying simulator have just been revealed.
Those early buyers will get an exclusive “Knight of the Order” outfit to wear throughout the game, as a reward for taking a punt on a game before it’s released.
While there’s only a Steam demo out there at the moment, an Xbox Live one should be following on 5 October (which is also the date the full game is released on that platform).
PC users have to wait a little longer, until 12 October, for the full release.
