*Update* Borderlands 2 Beat Terramorphous at any level/guns with trap door glitch

I made a better video actually capturing the glitch in action. It took many tries to catch on video. If you just want to see the glitch itself go to 2:15. Doing this you can potentially beat him at any level with any basic guns, it will just take longer. This takes me a good 20min with level 50 blue/purple guns.
