LAZY SOLO METHOD, ONE CONTROLLER:
You do not need a second controller, nor do you need to ensure a 1-1 or 2-2 score before heading into overtime, nor do you need to play in the AquaDome.
• Exhibition Match with one controller
• Game Mode/Arena: ANY
• Team Size: 2v2, 3v3, or 4v4 (anything other than 1v1)
• Bot Difficulty: NO BOTS
• Match Length: 5 MINUTES
It's you alone because there are no bots, but you'll get the MVP award because you set the team size larger than 1v1. Wait 5 minutes doing nothing, so the score will be 0-0 heading into overtime. After overtime starts, score a goal.
It's as simple as that. The achievement will pop at the scoreboard.
