Portal
This is a simple portal to look or shoot through walls. It would
be great to use these in CTF or some other team oriented map. The
portal moves with a button because it will do damage. If you get
pinned when it swings open, you may die. If you place more than one
in a level, remember to change the TEAM key for the FUNC_DOOR_ROTATING.
The prefab includes the button, so also remember that it has TARGET and
TARGETNAME keys if you use more than one (wall, room, lights and RL not
included).
