it's been a while so idr quite how it behaves, but iirc due to what we yoinked as we were just trying to get it up for some friends as there wasn't one yet when the jumpscare plays the audio is heard nearby and the image is seen by anyone with it on screen, it auto zooms you in synced to enough zoom for 1080p iirc or smth? so it full fills your screen and also closes menus
reminder factorio mods require all players to have them so if you want to prank your friends then I would recommend downloading the mod and changing the name along with setting the variables and making it so there isn't a setting menu for them, could then upload it with an inconspicuous name or send it to them directly or even just implant it in another mod you're going to use
ofc not an issue if it's irl and yr just trying to get them to play the game on yr pc or smth =w= hope this helps even if a bit late lol (but we all know how multiplayer goes so you probably haven't started the game with them yet lol)
