[quote name='CouRageouS']I don't think this has infinite spawning. I'm on my second playthrough, now playing Veteran and would say once a room/area is clear, its definitely clear.[/quote]
You're wrong. Infinite Spawning has been in all the CoDs and it's in this one. I'm playing on Hardened my first time and I have been so angered by it. Maybe since the fact that you've played through it already, you know where to go, but this is my first time and I've died so many times because I've been shot to the face by going through a door from an enemy who just pops up out of nowhere. I fear going into a building because this happens often.
There are parts where you can just run through and if you get to the next checkpoint, wherever that may be, all the enemies behind you disappear and new ones pop up from out of nowhere and you can kill them all you like, they keep spawning more to take their place.
I'm at the mission One Shot One Kill and I am just barraged by enemies that keep coming from outside my line of sight. It's a very very poor design to have spawning enemies in any game imo. I hate it.
