I am looking for to play L4D2 with you but... currently I am in the world of hurt, because my suffered major trouble and need to be fixed, shortly after my PC trap in the BSOD hell, I wrote resent updates on F.E.A.R. wiki, hoping they will understand why I not write the walkthroughs yet. And sorry for vanishing after a few messages, that day everything went south, not to Antarctica but to Argentina. I estimate I will fix a crapload of problems in few days, until then, see you.
Well, CZ bots (or ZBots) have problem with navigation in this maps. But POD bots... you can edit the waypoints to fix their movements. But it okay to delete it as I don't play escape maps often due of begin bugged.
