This cheat works for Worms and Worms United. Type in 'BOBJOB' or 'BAABAA' to access cheat mode.Now you get the minigun instead of the uzi, sheep, banana bombs instead of cluster bombs and you can go 360 degrees on the ninja rope. Now select the Bazzoka, right click to bring up weapons, hold down F1 and SPACE and select the minigun. Now about 50 bazzoka shots are fired where you aimed.

First select uzi aim it at the worms you want to kill and press F1 and fire at the same time hold for 1 sec. and realease this turns all uzi bullets into bazooka bullets.

Now, this isn't really a cheat, it's more like a bug. 1. Select either the bazooka or the shotgun (it might work with some other games too, i don't know). 2. Jump on a mine. 3. While in the air, press the fire-button. 4. When you land a shot should go off. 5. Now you have unlimited shots in that turn. And because it ignores the time-limit, you can fire until the active worm falls down and dies (jumps out of the screen and so on). I only have the demo-version and therefore I don't know if it works in the retail-version.

Most people know the cheat to type baabaa and get more weapons. However, there is also a little known cheat which can be very effective as it causes you to fire a stream of about thirty bazookas. Firstly aim where you want it to go. Now right click to bring up the weapons menu. While that is there press and hold F1 and the spacebar together. Still holding these down click on the uzi or minigun with the mouse. Voila. Not only will it kill your enemies but make massive holes in the landscape.
