MINERVA - read-only archives

I made it to part 3 on my own. Whoo Hoo! Now I am desperate. My weapons were taken away, I took the elevator to 3, went down the ramp to 2, and am stuck in the room with the white globe behind the force field. I cannot exit the room as the door is shut at the top of the ramp. Please tell me how to get into one of the weapon rooms, and where I am supposed to go. In a nice way, of course. Thanks !

[edit: title]

What's triggering that force-field, and is there anything which can be done about it?

I don't know what is triggering it. That is why I am asking for assistance. I did not see any plug, switch, or light.

Think about when you were a little kid and you had to "improvise" some height to get to the cabinets

look on the right wall, up a bit higher than head height. I personally just jumped and threw som,ething at it, but you could just make a tower of (items in that room)

Okay, I figured it out. I got the generator disabled and the great voice that doesn't really talk fired on the facility. I got my weapons back, killed the headcrabs and went down the elevator. This is where I got stuck. Where do I go?

-EDIT-

I downloaded the patched version and that solved my problem.

Now I'm at the part where you have turrets to hold back the hordes of zombies and I don't know where to go from there. I went up the stairs and killed the piggyback and the zombines but it's a dead end.
