What happened to the Shotguns?
When Windows tries to take a Shotgun he breaks the safety glass and takes it, that much is obvious, but when they all confront him along with Garry who right afterwards gives up his gun and Macready assumes the command with the weapons and orders, WHAT HAPPENED TO ALL THOSE SHOTGUNS?
There were like 4 or 5 shotguns along with the bullets. They (or macready) might have hid it but where? Locked it up? Who had the keys? Lock or hide the shotguns away but why keep the flamethrowers?
If Macready did lock them or did hide them away, why not reaquire them again when he fought in the engine room?
