A bit unfair in the city 17 part because too many enemies spawn, but otherwise, a neat map.

old relic of the past

So the Zom part of this campaign seems to be rather busted, the rebel has a habit of getting stuck after opening the door, won't open any of the locked doors (including the one with a keypad) and when they ask you to "find another way around" because of a door being locked nothing happens after what I can assume is that you're meant to destroy the barricade keeping that same door shut from the side the Combine soldier is on.

I like this map
