VIDEO (with Fast Swim):
http://www.youtube.com/watch?v=j3akxRy2tgEUPDATE: just to let you know, it's available with
StepS weapons v5.0.
Enabling Swim Suit allows you to swim in water, as deep as the bottom of the screen.
When TestStuff is enabled, swimming worms can stay in water inbetween turns.
When the game ends, all swimmers will drown.
To kill a swimming worm, you can use a missile (bazooka, grenade, animal...), aqua sheep, gun, hug with underwater jetpack, etc. Except the mines.
Enabling
Fast Walk will enable Fast Swim mode (max speed is doubled).
One known bug: sometimes you can't shoot rope when jumping out of water (maybe WA bug). This doesn't happen with TestStuff. Quick solution: touch some piece of ground before the rope shot.
