Gerald: That's an interesting point you bring up, Jason. This ruined facility offers many different avenues for attack, so watch your back. This map pack is very nice if you don't want to worry about a tank coming up to ruin your day.

And like the other two maps it's infantry-only. The other two are Imperial Japanese versus U.S. It should be noted that this is the only map of the three 'conventional' maps in the DLC that is German versus Russian. And yes, there was definitely camping going on (I'm looking at you, Andy). During the capture-the-flag session, the industrial nature of the setting offered lots of places to camp and wait for your prey. This map felt very cat-and-mouse I felt I was always chasing someone who was constantly turning the corner on me. All those giant pipes that you can crawl through, all those openings in the pipes that let you shoot at those outside (and, in turn, get shot at). Jason: Corrosion strikes me like some kind of weird, industrial water park. Of course, it didn't help that the members from both teams were all in the same room, so when Gerald started yelling false information to misdirect the other team to where he was holding the flag it added another layer of entertainment to the already crazy chase. That match went on for a long time with lots of places for the flag carrier to stay out of easy view of the other team, but plenty of little gunfights breaking out as opponents encountered each other.

It seemed that at any given time both teams had the other's flag and were alternately sweeping for the other team's flag carrier. Andy: Yes, I was struck by the multiple levels - as well as the various tunnels and corridors winding through the buildings - and how they made the CTF match we played first a real cat-and-mouse game.
