Very straight forward. Press
to start the game. When the notebook opens, choose "Versus"... unlocked after level 3. Add another gamer by pressing
on a different controller and choose a profile, or log in as a guest. Choose a map and start the match. The match is around 5-6 minutes. You don't have to do anything, just let the timer run out and when the score sheet pops up, so will this achievement.
**EDIT** Thanks to Reanimated Dan, he says that Versus unlocks after level 3. Thanks Dan!!
