Hey EA, you might want to patch Battlefield 3, because there's apparently a game-breaking exploit. According to YouTube user DarkSydeGeoff, this is it.
Using the exploit, detailed in the above video, players can get over 100,000 XP per game.
Here's how the exploit works: Join a "Hardcore" game with a buddy on the same squad. Then, both chose the Engineer, and one of you needs to select the robot. The other uses the repair kit. Either you or your buddy shoots the robot, and then the one with the repair kit fixes, or heals, the robot.
And that's it! In the video, DarkSydeGeoff got 400 XP in under 10 seconds with the exploit, which Kotaku has yet to test.
No doubt EA is going to patch this -- as EA should. But when?
