Forge physics glitch
From Halopedia, the Halo wiki
- Start a Forge game over Xbox Live with at least two people.
- Have Player One spawn a wall and set the physics to phased. Have Player Two stand on the place where they want to get under.
- Have Player One with the wall push Player Two, and then have them fall under the map.
- If Player Two goes into monitor mode quick enough, he can survive and fly around outside the map.
