Again, we have discovered a huge glitch in Halo 2. This glitch allows you to completely freeze the AI. As far as I know, this glitch only works during the battle against the Prophet of Regret. We don't have a fully working method yet. So we won't release a video or tutorial just yet. In fact, to achieve this glitch, we actually needed some assistance from mods. It's nothing major. Just a no-clip mod that allowed us to walk through walls. Once we were partially inside a wall, all we had to do was punch the wall and that froze the AI. We're trying to find a way to get inside the wall without mods. But for now, this can only be done on the PC version of Halo 2 (Halo 2 Vista). I'm not sure if you can do the same thing on the Xbox version. Here's a screenshot at one of the effects of this glitch.
