Type "Total Carnage" on the main screen to start the game with a banana bomb, three sheep, and a mini-gun. Also try "TOTAL WORMAGE" for a special weapon, Sheep Mode. If you're using a joypad, press 'GREEN', 'UP', 'PAUSE', 'PAUSE', and 'YELLOW' (which spells "GUPPY", a tribute to the late Bananafish). This gives you three sheep, one banana bomb and a mini-gun straight away (go into Weapon Options if you need an UNLIMITED SUPPLY of sheep).

The "Hidden Prod Move": stand next to a worm other than yours, then press: 'AWAY' twice followed by 'TOWARDS' twice, and finally do a prod to receive a secret move.

The "Legendary Prod Move" is a not available in any shops. To activate it, get next to your victim and press 'AWAY', 'AWAY', 'TOWARDS', and 'TOWARDS' (i.e. if your worm is facing right, press 'left', 'left', 'right', and 'right').

Here's how to change: friction and/or gravity for custom screen mode. The template for a custom map is name.wxyz.wrm.

You can also make your own message appear when your level is chosen, by giving your level file a file comment. Do this by clicking on the level icon with the 'Left' mouse button (i.e. selecting it) and choosing "Information" from the Workbench Icons menu ('Right Amiga' - 'i').
