O5 Keycard

The O5 Keycard, sometimes jokingly referred to as the "JC Pennys Black Card" is a very expensive card which allows you to open the room of the great cock sucking evil and also the Alpha Warhead Control Room. It is the best Keycard in the game, having permission to open everything.

Advice:

If you see someone with an O5 Keycard, disarm / shoot them so you can execute the omega lulz.
