This campaign gives me mixed feelings towards it with some flaws in each maps

Map 1 seems fine at first but I kinda don't like long intros. Next is that it is very narrow spaced and claustrophobic.

Map 2 has a train that would kill you instantly. But with bots not aware of their surroundings, progressing the map without teammates would be nearly impossible but thanks for the defibs, it has gotten easier.

Map 3 is too dark and it has nothing but a thick forest. Seriously, I can't see anything, not even the flashlight helps because the trees are blocking my view. It's like I'm roaming around blindly regardless I know where to go or not.

Map 4 has a very confusing map layout and the fog doesn't help much. To make things worse is that you replace first aid kits with defibs. Must I remind you that bots don't take defibs? That would even make the finale harder to finish. I can't imagine how this would go on expert.
