Bugs

 * Occasionally in V.A.T.S. mode, if you are standing near an npc or follower, upon exiting vats, you may become stuck in the ceiling, and be unable to get back down. Reloading a save will fix this, or for PC users you can use console commands.
 * During battle with the ghouls the player may find an extraordinarily hardy feral ghoul reaver which, due to some collision issues, appears to be twitching uncontrollably. In most cases the reaver can only be killed by much gunfire under V.A.T.S. Occasionally when the Reaver is killed it may fling back down the hall where it came from.


 * Sometimes when using V.A.T.S. mode, the shots made from your gun will fly around and will not hit the target, regardless of the chance to hit them.

Behind the Scenes
The system concept and station design is based on the Capitol Subway.
