The Chilli Con Carnage is a weapon exclusive to Worms Forts: Under Siege, accessible through the Keep. When fired, a stereotypical Mexican hat on a blue object launches into the air and explodes when it stops moving, similar to the Holy Hand Grenade. The explosion is powerful, and releases a couple of clusters that explode on contact. The area it touches will contain patches of fire that can damage worms and delay building reconstruction.
