There was a guy in that cage who said “help finally came” or something then his buddy ate him… and there’s nothing else in the room and I’m not sure where to go. The door where the guy is, is locked.
You’ll need to keep that zombie from killing the guard if you want him to unlock the gate. 
I’m stuck in the freezer part early in the game, after you meet up with another security guard who tells you the army is coming, then pass a cafeteria and get to a big meat locker. I can’t find the switch to move the crane so I can go from one vent to the other.
look on floor for a wheel pick up and place at wall u will see it if u look…
Hello,
I read on the wiki that it can be first acquired in office complex. Didn’t find it there.
At the beginning of “We’ve got hostiles!” it’s in the security office to the right…taunting me.
I have searched every inch of this level trying to get in with no success. Am I missing something?
I got it in we’ve got hostiles, in the security booth. I don’t think you can get it earlier than that.
Yep, right before Blast Pit. Looks like there’s a mistake in the wiki.
It’s probably based on HL1, you can find at least one or 2 of them in the original.
The Wiki you’re reading is as Solokiller said, Based on half life 1,
Due to Black Mesa being a Remake of the first game, While most of the gameplay is very similar to the original some things are slightly different,
I found myself running around at the start wondering why the Guard kept telling me to shoot things, thinking I had overlooked a gun and missed the crowbar, but then came across the crowbar a few minutes later.
I’m just passed the bit where you meet the guy whos friend got bitten by a headcrab and you get the .357, but after that there doesn’t seem to be any way to progress further. Anyone got any idea?
It looks like there is a valve missing a round top, but I can’t find it.
That security office in We’ve Got Hostiles is accessible only at the end of the chapter. You basically come back to that area in order to open the silo door (as that scientist was screaming to do)
Im also stuck there exactly there, anyone know how to progress? 
Alrighty guys, found the way now. One hint; Cafeteria Vents.
So I’m guessing the first Shotgun you have access to is dropped by HECU Shotgunners?
Actually, you get it pretty soon after you meet the screaming scientist. Just work your way through that level and you’ll end up in that grate the scientist got pulled into, and land into his office.
Hello,
could somebody give me a hint how to get to the alternative route in Office Complex? I’ve been going through the level two times but I didn’t find anything. Also, what about mentioning it in the Wiki?
Thanks.
The same as in HL1
Human grunts don’t use shotguns until after you encounter them in power up IIRC.
