Create two human-controlled teams. Then, start a normal
multi-player game. Create a long, flat landscape for the game,
with no objects or bridges. Make sure there is not an indestructible
border up the top, or none of the explosives that fall from the
air will be accessible. In the game options, set the probability
of getting a weapon crate to maximum, and turn the probability
of getting a health or utility crate off. Turn invincibility on
(or set the energy of all worms up to 200). Turn mines and gasoline
cans off. Change the turn time to 90 seconds and the round time
to 30 minutes. Then, in the weapons options, go to the crates
section, and turn all crate probability meters to nothing, except
for one weapon, which you should turn to one crate. Also, if you
have completed mission 4 in the missions section, turn jet-packs
to unlimited. Make both teams in the game contain eight worms.
Start the game and play as both sides. At each turn, press [F12]
once and "Skip Go". Once there are five crates on the
landscape, do not "Skip Go". Instead, go and collect
them all. Use the unlimited jet-packs to get places faster. If
there is nothing there, then "Skip Go" again. Although
it may seem very long and tedious, surprisingly it moves along
quickly. Keep repeating this, until after about fifteen crates,
one of the secret weapons will appear in a crate. Try out all
the special weapons, such as the mail strikes, and Salvation Army
ladies. Press R midway through using each weapon to see
their effects in slow motion.
