Player patrols the top of the castle and drops rocks onto the Orkish enemies who are trying to scale the wall. Should an Ork make it to the top then the player can call for their trusty sword and chop of the offending invaders head. What makes this game difficult is that there can only ever be one rock on screen at a time and while the player is holding their sword no new rocks will appear.

Randomly throughout the game a chief Ork will appear. They ascend slower than their companion Orks and can only be killed by dropping a rock on their head.
