Lock people out of elevator on "No Mercy: The Hospital"
Note: This is a very tough trick to do. Once everyone is in the elevator, order one person to get outside of it. To do this correctly, the person that is going outside must be slightly in front of the blood spot of the elevator. That way, the game thinks that it is safe to close the doors. Immediately start the elevator the moment the person starts walking out. If the timing is perfect, it should work. Note: This was done while everyone on the server had a two bar connection, resulting in no lag but causing events in the game to slow down at parts.
