Mike's Secret Laboratory: Easy tutorial win
When you start this mission you should be to the right of the big protective screen. If you go forward slightly you should see a platform to your right. Use a Jet Pack to get up there. There should be a weapon crate up there. If you collect this crate you will get 25 Sentry Guns. Use these on a flat piece of ground. Then at your next turn, go close to the Sentry Gun and fire it at an enemy worm. The Sentry Gun should detect this and will fire lots of bullets at the worm you shot. Note: You can only use one Sentry Gun at a time until it is destroyed -- place it carefully. Also, this is not the only other time in the game you can use a Sentry Gun. The other is on the last level, where you only have two of them.

Nice To Siege You: Easter Egg

Easy trophies
For the "Barrel Buster", "Big Blast", "Animal Lover" and "Body Count" Trophies and the damage trophies, create a scheme with just a Sheep and set land object to oil drums. Then, start a multi-player game. Put four human teams in and fill up the sixteen Worms. Then, use the weapon scheme you just made and select landscape. Choose Camelot and type the number code "3651335800" to get a tiny arena. Then on Wormpot choose double damage, super animal weapons and super random weapon. As the sheep is the only weapon in the scheme, the random weapon will always be the sheep. Then, start the game. Fire the sheep and detonate it. The explosion will destroy the entire arena and the barrels, kill all the worms, and do about 5,000 damage (which will give you the big blast). The round will draw and you can repeat. Repeat this until you have killed enough worms, caused enough damage, and destroyed enough barrels to get the other trophies. This will also give you the 3 and 4 Baggers and the Beast Within if you do not already have them.
