Like Toribash and Rag Doll Kung Fu, Triachnid is based on ragdoll physics -- that is, the character you control is a jointed model that behaves according to the rules of physics. In Triachnid, you move your three-legged character by picking up its feet in turn with your mouse, and flinging them against a surface -- since your character is bug-like, the feet can adhere to almost any surface, and you can climb sheer cliffs, or even hang upside down.
