How to make your scorpion fly!
This glitch was done on the campaign level ‘Delta Halo’. This glitch can be done on any difficulty. When your reinforcements arrive with the scorpion tank right after you lower the bridge to the wraith tanks, grab the scorpion tank. You will need the scorpion for this glitch. Go through the series of tunnels. Go through the first clearing where there are the ghosts and plasma turrets and in the center of the area, there is a little water source. Go through this area and make your way through the rest of the tunnel. When you get to the next area with all the plasma turrets lining the structures, make your way with the scorpion to the top were the pelican drops reinforcements and weapons. In front of that spot, there should be multiple stationary shield generators. (Blue shields that turn red when fired at with plasma weapon) Use your scorpion tank and destroy them. Then, quickly before they regenerate, place your scorpion on top of a couple of them and get out. When you get out, wait for the shields to regenerate. When they do, (it might take a couple of seconds), the scorpion should fly through the air. If it doesn’t, wait for the shields to regenerate and wait again. If it doesn’t work, then restart from last checkpoint and try all over again, this time trying a different position until it works. If done right, it should fly through the air. When I found this out, I got the scorpion on the high ledge to the left of the shields. Also, for another fun trick, you can stand on top of the scorpion and if done correctly, you might fly up and live. When doing this, I made it to the small ledge to the right.
