Stuck on mission 2: Free the rebels that are in Dr. Hoffmans lab.

I have been to every room that i know of..played with all the computers..looked for key cards and all the bad guys are dead... but not having any luck. There is a room with a force field on the door that i think I need to get into...have not been able to open it.
Any ideas?

Here's the thing about Crusader - if it has a force field, you're going to have to get in there. Somehow. There are usually three things keeping a field active:

- key card
- wall switch
- power generator (looks like a big green and brown power unit, may have electricity arcing around it.)

My general rule is that when I see one of those power generators, I blow it up because it's probably supplying juice to a field or an automated gun turret.

still no luck....this one has really got me stumped.

Playing through now. Is this force field found on a smallish room in the center of a big cross-shaped (or x-shaped) area with four hallways headed to the four compass points, with a sort of big storeroom to the north? I got stuck there, too, even though I've finished before.

If that's where you're stuck, then head north to the big storeroom. At the north end of the storeroom, you find a small glassed-in room. On the doorway frame is a pad. Activate it to open a little closet thingy inside the glass room. A terminal is then exposed. Access the terminal and the field drops. The door also opens.

First time through I ignored the pad since those usually open a door right there. Not this one.

Oh! I;m going to give that a try right now. I know the panel you are talking about..i just started watching a youtube of the level and recall seeing it.
Will report back! thanks!

That worked!! Thanks so much!! That room didn't even look like it was there untill the walls lifted!

Ah, this takes me back to the olden days where you crowd-sourced from friends to get through games : )

Yeah, this one was a bit sneaky. I mean, the pad is in plain sight but one doesn't think to use it since the door is already open. So the player instead cruises right by to activate the button on the pedestal just outside that room... and nothing seems to happen so you waltz back to that central room to find the door closed. Crap, maybe I screwed it up somehow. Go back to the button and hit it again. Same thing. Then look everywhere else to find that hidden switch, button, whatever, and completely ignore the one right in plain sight because the game has trained us, up to that point, that the door pad opens the door that's positioned right next to the pad itself.

But not this time. Sneaky sneaky.

You hit that right on the nose! That's exactly the way it went down!

I was stuck at exactly the same spot, your instructions allowed me to proceed, so first of all I feel obliged to thank you for your precious help.
At the same time though, let me tell you that I truly HATE this kind of things!
I had already found something similar in Turok 2 not long ago, and now this... it has already marred my enjoyment of the game. A pity, since it's turning out to be great and actually deserving its status.
I know, I know, "old PC game" and all that, but frankly, it's one of those things I don't miss from back then, and I'm glad that game developers, by and large, have learned to avoid recurring to such tricks (sometimes to the point of engendering in gamers that well-known feeling of "being taken by hand" which, to be honest, I dislike too, though not as much).
Please excuse my rant.
