Worms 2: Armageddon

This trophy requires you to reach the Vital Crate without you using the Bridge Kit in your inventory. Although you cannot use the Bridge Kit, you CAN use Girders, as the description mentions nothing about these. It should be noted that this mission is much easier if you kill all enemy worms first. This way, you won't risk your Girders being destroyed by enemy fire.

The enemy worms in the mission are particularly accurate, so cover is vital here. Move out to shoot and instantly retreat back into cover afterwards. Avoid leaving your worms out in the open, or on a high point on the map, as this will likely result in a very early death. Use a combination of Grenades, Bazookas, Homing Missiles, Napalm Strike, Banana Bomb, and Poison Strike to take out the enemy worms whilst referring to the general tips and suggestions section listed under the Head Hunter trophy. Unfortunately, there isn't really a set tactic on how to remove these worms, as their shots and movements can be very unpredictable.

Once the enemy worms have been disposed of, it's time to cross the water. You need to choose a place on the edge of your Fort where you feel comfortable placing 3 Girders to get across. The most ideal place is from the top of the palm tree if it is still intact, as you can easily make it across the water and jump to the other side, however, anywhere in this general area should suffice.

When placing your Girders, make sure that they are at an upwards diagonal angle. The reason for this is that you will need to jump onto them, walk up to gain sufficient height, and then jump down to the next one. This means that all three of your Girders may need to be at different heights, starting high and slowly getting lower. The picture below shows the ideal position to place your Girders:
 

Another method is to use the Parachute to slowly drop down from the tower and instantly land on the other side, although this is harder to achieve. If you try this tactic, then you should aim to land right at the bottom left side of the enemy Fort (where the fishing hook is.) Having only one arrow of wind is the perfect scenario for this, so keep skipping your turn until this happens.

Once across, use all remaining Blowtorches to dig through the land to the crate. If you don't make it, then the Buffalo of Lies is a good option for clearing space, however make sure that it doesn’t destroy the crate. If you're near the crate and are worried that it could get destroyed by any further explosions, then you have three Shotguns which are ideal to shoot your way through the land. The beauty of Shotguns is that they don't make an explosion when they hit terrain, meaning that you'll be able to shoot right through to the crate without fear of destroying it.
