Worms W.M.D

This is the hardest trophy in the game. You have to complete all 90 sub goals.

Most missions are quite straightforward when it comes to the sub goals; however, there are a few that stand out. My advice would be to play through each mission normally, making note of the sub goals and actively trying to achieve as many as you can in a single playthrough of any mission, and clean up any you may have missed afterwards as you do not have to complete them all in one go.

The hardest sub goal by far is keeping all of your worms alive on 'Tsarface'. My strategy was to take out all worms on the left side of the map and then use the OMG Strike on the Sniper in the tower, then I kept crafting industrial magnets and placed them near my worms to deflect any shots the enemy fires at you whilst waiting for sudden death to activate so all enemy worms drowned. This is the safest way to get this sub goal completed.

There is an excellent playlist of every mission in the campaign showing how to complete each sub goal by Pete the Sheet Here.
