I have another rather peculiar glitch that came from Halo.
When I was playing on Assault on the Control Room. I was playing with my dad (he's a big Halo Fan), we accidently dropped the tank over the edge in the large underground room when I was out getting ammunition (whoops!), which forced us to walk and all of the surviving marines (some fell off the edge with the tank! I felt terrible!). When we exited the large room, we approached the area where we get warp in the large tunnel. When I got warped by my dad I realized something: The marines were no longer following us. I look back to see that they have frozen in place due to some glitch....
This is when I decided to toy with the situation.
I found a needler and fired a bunch of rounds on a marine, amazingly, the needler rounds didn't explode! I was able to coat this poor marine to the point where he was a giant, purple porcipine. After that, I started sticking another marine with plasma grenades. They didn't go off...until I missed onced. The grenade that missed the marine went off, blowing up the ones stuck on the frozen marine, and blowing up the needler rounds that coated another...I flew...far...
I wish I had a video of it...it was one of my best halo experiences ever.
