Sentry gun

Sentry Gun is a autonomous weapon available in Worms 4: Mayhem. It is a six-barreled Gattling gun with ammo fed to it from a box on the contraption. After it has been placed it will fire a big round of bullets at any enemy worms that get in range, but it can fire only once in the whole turn, this can be used as an advantage to fool the gun to fire at the landscape to waste it's ammo so you can safely destroy it. It inflicts approx. 25 damage in one salvo. It takes approximately 4 or 5 shots from a Bazooka to destroy it. It smokes and later explodes, getting extra damage to worms nearby. Because of it's ability to fire by itself, only one sentry can be placed until destroyed. It is unlocked with the The Kitchen Sink weapon scheme. It also appears to be able to "move" when selected for placement twitching its four metal "legs", which may say that the gun has limited AI.
