Unfortunately CS really lacks in that aspect. Personally I enjoyed the exploration and underground atmospheric scenes in SoC. And the game gets more 'hectic' by the end. But since all the maps are split-up instead of sewn together it really doesn't work in the end, and there's no reason to rack your brains trying to help everyone.
The beginning of Clear Sky is totally awesome, the faction war starts off really cool.
I like SoC a lot more than CS I have to say. And then there's an endless stream of Bandits spawning in another scripted scene at the Red Forest. 'Zombies' re-spawn there like no tomorrow, and your allies really aren't any help to you as your lucky if they manage to kill any of them let alone just get shot to death.
There just seems to be a lot of scenes with 'endless' enemies. Yeah, it really is more of a 'Shooter-shooter' instead of a 'survival-shooter' which is what I'd kinda classify the first one as.
