Glitch: Flood a Worm
Note that this glitch works if you are playing multiplayer game "yourself vs. yourself", and have flood and freeze. First, select a map that has a edge surrounded by water (for example "Coloseum of Doom"). Second, get a worm to go to a edge that's surrounded by water. Third, when it is that worm turn (or just use worm select), open the weapon panel and select freeze. Fourth, when it is the enemy's turn make him do flood and the ice cube will still be there but the worm wont be there!
