that's what I was afraid of. I have tried it 20+ times and can't seem to make the jump (and my head explodes the long way around past the terminal on the wall). Wow - this feels like Mario Brothers - if I see a turtle I'm gone.
Well.. I could be thinking of a different spot and making it harder on you.. the room I'm thinking of it is obvious you can jump from the catwalk onto the beam, and then pop up again into the doorway.. though at the time I didn't know that was the way I needed to go just wanted to see if I really could.. it just happened to work out..
..so if you're struggling with it, you might be somewhere else trying to make an impossible jump.. because it's only two quick, fairly short, jumps and shouldn't be too hard to pull off.. your Mario Brothers reference is fitting tho.. so it could be the same.. now that you mention it, that's kind of the vibe it had..
