go to your right - there is an open door 
It’s not needed to get through the door where you find it in the original, look around!
You’ll figure it out.
You find the crowbar later on.
This is probably just me being stupid, but I remember in the original game the switch was right on a wall behind the freight elevator next to a dead security.
In this version (which I understand is not an exact replica and will have some layout changes) the switch is inside a security room with two locked doors and two unbreakable windows.
Like I said, I’m probably completely overlooking something and having a brain fart, but I have no idea how to get into the security room. I see a bunch of boxes leading to an air vent (which was not in the original game) but i cant jump high enough to get up there. Any help would be appreciated considering a full walkthrough for this version of the game is yet to be made.
Can you supply a screenshot? (Press F5 ingame, I think…)
scientist shows you the security room, where the weapons are
and there’s a chance to power up health
But after that – I’s foxed – going back no good
and the doors are all stuck near to the weapons room
even after trying a grenade on each :fffuuu:
If I sit here any longer I’m gonna have me a severe case of asteroids !
Have you tried the duck-jump? (Crouch and Jump immediately afterwards… have to use it all the time).
I am stuck here btw. none of the doors in this area open. i cant reach the one on the balcony to the left.
Apparently, you’re supposed to jump onto the boxes and into the air vent…that’s what I just saw somebody do in this walkthrough vid; he made the jump with zero effort.
But in my situation, like yours, I cannot jump high enough there for the life of me. I’d like to know the the explanation/remedy for this, as well
Here’s the full room.
The two locked security doors.
The two unbreakable windows.
And the boxes leading to an air vent which I cannot jump high enough to get onto.
Okay, thanks a bunch!
There are two valves on red pipes, if you close both of them (takes some time, keep E pressed), than you can proceed somewhere downstairs if I remember correctly
I was a little confused as well, but yes, the crowbar makes an appearance a little later than it did originally…you’ll come across it eventually.
Just figured it out…like someone said earlier, you have to crouch jump.
Without having been so far, the air vent screams “JUMP!” to me 
The bunny hop/duck jump is a little tricky in this game, but it looks like it should work…
So I tried the duck jump again and got it to work. Thanks.
Is it just me or is the control for the crouch jump a bit complicated? I understand it’s not incredibly complex but you have to time it just right or it doesn’t work.
Absolutely… little tricky
Found it. Had to track back a little and go up into one of the vents…
Man there is a lot of crouch jumping in this game 
Press the elevator’s button and move on.
I’m just glad I got through that. With the exception of the crouch jump controls this is an incredible overhaul of the original.
Problem solved.
Before jumping, run. 
Like in real life.
