Use the cheap and effective spring trap to launch pesky enemies through the air. Where they land is up to you - a pool of lava, a pit full of acid, or even straight into another trap!
What's the best cure for an orc's migraine? Keeping hitting him on the head until he's dead! The pounder gets the job done at a reasonable price. Throw a few tar traps or a decoy underneath; by the time the orcs think to look up, it'll be too late.
Robot Entertainment has released a new Orcs Must Die! developer diary that offers a comprehensive overview of the game as well as a look inside the development process.
