There is a way to do corruption on Rupture Farms (and if you do it it will corrupt the whole gane not just Rupture Farms), you get to that secret that you have to grab that thing up there and fall into the pit it opened near the statistics where it says how much Modokons were saved, how much died etc, then you do infinite granades glitch and get 11 granades you kill the guard slug with one granade, then you go to the below floor and go back up to respawn the bird portal, then do that pray thing that Abe does you get hit by that praying detector or something like that, the granades will fall into the ground, you go to the bird portal at just the right time, then it will crash more than half of the time, but if you get it right A LOT of graphics will glitch the hell out, and it isn't just the graphics it also aphects the CODE for some objects I think because while this glitch was activated I was in that part of Rupture Farms where you are told to save the Modokons and you have to lead them to a bird portal, I activated the portal with no Modokons around and I ENTERED THE BIRD PORTAL that wasn't made to possible for Abe to enter it, and it crashed.
