Anyway, the laptop was a way of having a lot of functions available to you without taking up equipment slots.
What the hell was I playing? Does this sound like another door game that could be mixed up with OOII?
Well, the closest thing in UT2004 is the AFB. You need access cards to get into it, and you if you make it down to the lab you can get upgrades like a built-in galaticom, or trikorder....I think you need a floppy disk to access the missile silos though.
As for a "laptop" in a game, I can't say off the top of my head. I only played a few door games though, have you tried the BBS game on bbs.operationoverkill.com?
