Hole in the Highway
From Halopedia, the Halo wiki
Template:Diagramneeded In the last part of the level Outskirts, you make your way through the enclosed highway. Partway through, a Scarab blasts a hole in the roof. The glitch is that you can climb on the debris and jump onto the untextured roof. Though Grenade Jumping helps, it is not neccessary. If you do it fast, you can see the Scarab walking away and then disappearing.
