I just got done playing a ton of this over winter holidays, but I can still never remember how the sewer or the intelligence hallways work. Even in the game I get lost in them.

I would like to try the original 2fort4, but all I remember of that one is that it was really dark inside the forts, and the room with all the ramps was a complete grenade mess. I should remember better, because I spent 2 – 8 hours a day playing that one summer.
