Found a bug in the game. There's no button to call for help when the elevator is stuck in the first map!
No seriously, been messing around on my 2nd playthrough (easy this time ) trying to find the prod that's supposedly in the map somewhere.
Anyway I took a trashcan with me on the elevator and pushed it toward the opening as the elevator was going back up, the trashcan broke and the elevator stood still, now I'm stuck!
