Hit Point Reduction Trick: 
Turn the timer off in the Options menu, and then in the 
'Weapons' = option, press SQU+X (x9). While playing, pause the game,
press Select = and select Extra Time. All the worms should be 
reduced to one hit point
(Matt "Snacks" Gustavson)

Sheep and Banana Bombs:
On the weapon select screen hit the following buttons for these 
new weapons: SQUARE and
CROSS (10 TIMES)

Full Weapons:
     Press pause, then:
     X, S, S.
     X, S, S.
     X, S, S.
This will give you unlimited Banana Bombs, Sheep and Minigun.
 It will also make your Ninja Rope even flexible
using left/right to control it.

Uzi Rockets:
If you select the rocket launcher whilst firing the Uzi, you'll fire 
the rocket launcher as if it were an Uzi.

GENERAL TIPS:
When you are about to use a homing missile or airstrike, 
move your worm to a safer area where possible.
Under an overhanging ledge or similar, for example. 

Restrict teleports to one or switch them off, so that people 
really have to think about their moves and do not get
the chance to hide away. 

Make the digging tools limited as it forces people to attack. 

Air strikes are particularly effective against groups of enemy worms. 

Always check the wind; try against the wind shots for 
some spectacular results. 

Practise the method of swinging on the rope and being 
able to throw yourself up and over objects. 

Practise shotgunning mines onto other worms. 
Try and guess where the mines will go. 

Use the blast wave of explosions to move worms or 
mines in certain directions. 

Never stand on the edge of a cliff overhanging water.

Keep as high as possible and in the centre of the playfield. 
If you're too near the edge you could be blown off
the screen. 

When using banana bombs, try throwing the bomb into a small 
crevice -- the resulting explosion is incredible.

Set a long timer and use high bounce when you wish to throw a 
grenade down a tunnel; the grenade will roll and
bounce much more effectively. 

Try to use the shotgun more often in Extra Time situations as two 
shots are very effective in this mode. 

Use the rope to throw yourself off and hit other worms into the water. 

Turn homing missiles and air strikes off; rely on supply crates for these.

Remember that mines are proximity based so you cannot use them l
ike dynamite -- they will only explode if
another worm is close enough. 

The shotgun and uzi can be used in long range mode, try zooming out and 
picking off distant worms sniper style.


Try and win the match with a prod... guaranteed to annoy opposing players. 
The prod move is away, away,
towards, towards.
