The Gmod's thing.

there's a gman that does a loud half-life 2 stalker scream if you go near him, you can find it in the backrooms

its the oberserver he's trying to collect info on you for some reason nobody knows...

It's the source engine.

It's called having a lack of balls

edit: Its a source game thing i think

Just download Zeta players make sure to have nav

I only found some random friendly NPCs, and that black Gman down there in the backrooms section, where's a jumpscare if the player try to approach that Gman.

theres no jumpscare just a loud scream if you approach gman in backrooms (trust me he doesnt move) so its all fine

Now i feel safe, thanks guys

Yea there's a red skeleton in the backrooms which screams for a short period of time

I haven't seen the gman though

where are the passisve npcs

if you fly outside of the skybox for a while if you reach the right point gmans face texture will go on the screen and BAM REALLY LOUD SCREAM... this is not the gman virus

also in one of the prison cells in one of the areas there is a citzen npc just there
