castle-combat 0.8.1.dfsg.1-0.1build1 (i386 binary) in ubuntu feisty

 A clone of the old DOS game Rampart. Up to four players (or
 more in future versions) build castle walls, place cannons
 inside these walls, and shoot at the walls of their enemy(s). If
 a player can't complete a wall around any castle, the player loses.
 The last surviving player wins.
