I was re-doing the Sin of Damnation missions on normal when I realized that the heavy bolter was being assigned a random amount of ammo compared to the previous missions. Did I miss something about this mission that would do that?
Also, I find the Pitfall mission the easiest one to do the "no command point" achievment. Just use the librarian's block on the middle ladder and walk all the way to the exit on the first floor -- only have to face one gene stealer as the others bottlenecked on the bottom floor.
I thought that the exit point was only supposed to be on the lower level which is how I beat it the first time through but another exit on the first floor makes it too easy!
I just wish some thing were better explained like the extraction sequence. An "undisturbed term" to me meant that you're not attacked. Not that you have to move there one turn, wait another turn and escape the third turn. That's three undisturbed turns, really.
