In survivor mode the objective is to outlast your opponent by depleting their lives. But this can be easily boosted with just two people.
Simply start up a survival match and reduce the life count to one. That means the first person to die loses. Don’t bother with trying to kill your opponent as crossing over to the over side of the map is a waste of time.
All you need to do is take it in turns of taking a nose dive straight into the floor or ocean whichever map you are on. To make it go even faster click in your right stick and hold foreword. When you hit the ground you lose your only life and the opponent will win the game.
Do this five times and on your way back to the lobby, the achievement will unlock.
