So having finished SP, I've been playing around with SP and Co-op terrorist hunt, a great concept and highly enjoyable until it becomes a tad frustrating after being gunned in the back by a spawned tango that wasn't there 1 second ago when you last turned your head.
Watch the guy spawn at the end of the corridor :
This surely isn't how it was meant to be ? I wonder why all NPC's weren't programmed to spawn randomly at the beginning of each map and have them roam (as in CS) ? This game mode has very little to do with being an adept FPS gamer, but more about memorising spawn points for each map. Very sucky indeed I must say.
