Speed Kills Trophy
Win a multiplayer match with a 20-second-per-turn time limit.
This trophy means you have only 20s to act in your turn before it auto ends and the enemy turn will start and so on, but not to win within 20s. Go to Skulls On The Couch option, then set the Time Per Turn to 20 seconds and then chose the 1st map, then chose your color and add a host by pressing . Either you do an all out attack to kill the enemy General or bring him to a cliff and throw him a way for a fast end and the trophy will pop.
