After using the 'baa baa' cheat, select banana bomb or any other special and in the process of it being in the air type 'aab aab'. Although the cheat will have been taken off you will have another go so you retype 'baa baa' and use another banana bomb and so on and so forth!
While playing the game select the machine gun, aim, press F1 and Spacebar at exactly the same time to shoot. Instead of firing bullets you will fire bazookas at an alarming rate.
While playing, aim at the target (don't stand too close). Choose uzi. Then press F3 and F5 at the same time and press the spacebar to fire something nice.
Select blowtorch or drill from the list. Then while you are moving
through the dirt press Esc. Wait until your worm has stopped moving, and
press 'Return to Game.' Your worm will automatically start cutting through
the dirt again. This process can be repeated as many times as you like.
