+often referred to as a mixture of The Settlers and Worms.  In a simple 2D
+antfarm-style landscape, the player controls his crew of Clonks, small but
+robust humanoid beings.  The game encourages free play but the normal goal is
+to either exploit valuable resources from the earth by building a mine or
+fight each other on an arena-like map.")
