They occur with plot points, there are three that I am aware of, all of which are fairly obvious. Just keep your wits about you, but you don't have to sit in a corner and suck your thumb.

Aren't there only two? One in Lamda with Akers and one in Omicron with that L4D2 Witch-like monster? Where is the third one? (Despite my achievements saying otherwise, I have already seen the game all the way though thanks to LP'ers on YouTube but I thought the game was so fantastic that I had to get it).

Teleporting fishbowl head on the CURIE.

Yeah the third is when you unplug the power on the CURIE to use the escape vessel. He'll keep chasing you 'til you get to the vessel. He chases after you pull three plugs out of the four.

Ah, if only you could make them not as bad, like the monsters speed is reduced to 0 or they can't damage you.. Getting past Akers is still a ♥♥♥♥♥ due to that Elevator part even with the mod installed
