Worms 2: Armageddon

This will unlock on your first playthrough after completing Mission 4. This is effectively an assassination mission whereby the goal is to kill the target worm. The other worms don't matter so much here, but you may wish to take one or two of them out if they are causing you problems. The target worm will almost always skip his turn, so you don’t need to worry too much about being attacked by him. He is rather well dug in and protected, so you may need to consider making your way across to the enemy’s Fort by using either a Jet Pack or Parachute and Blowtorching your way through if you can’t reach him with your other weapons.
