Oh there is a bunch of glitches to discuss.
I know this was already discussed, but in AE, in the Slig Barracks, in the screen with 2 depressed mudokons, if you possess one of the sligs at a certain time, when one of them shoots at the possessed, the possessed shrinks down, instead of dying first. Also, in second hub of SoulStorm Brewery, there is usually a misplaced blinker. It gives no interverance though.
In AO, sometimes sligs don't stop walking and go off an edge or hit a bomb. I found this mostly happen in one of the Stockyard secrets. Also in AO, if your quick enough, you can touch a flying droid bomb and not die. Oh and once in Scrabanian Temple, in the level that's to the right on the lower level of the enterance, I found something interesting. One time, the 2 scrabs actually noticed each other and killed each other, even though there was a wall between them. That's all I can say. See ya.
