Worms W.M.D

Tanks are found in several main campaign missions, but you will very likely not unlock this naturally.

To farm tank kills, set up a local match with your own created scheme. Set up 5 human teams of 8 worms and set worm health to 1, go in to Objects and set Vehicles to lots, you can also go in to Crates and set Vehicle Drop rate to 100% to guarantee a vehicle spawn every turn and make sure to set Teleport In.

Once the match starts, you can use Teleport In to put all of the worms in a single spot and then shoot them all with a tank for 40 kills in a single round. Repeat this again until the trophy unlocks. You can track your progress with each vehicle on your profile under Vehicle Stats.
