Located around the map, you may find a special door that requires a key card. Inside, you can find various supplies that will help you survive the apocalypse.

There are 3 standard keycards and 1 high tier keycard that can be acquired either through events hosted by the staff team or as ground loot. Each keycard is assigned a color, which opens its respective colored door. (see map below) The red keycard is called a Punched Card, which opens the vault hidden underneath Tisy Military Base. Inside, there is the opportunity to find the best loot in the server, as well as the strongest caliber weapons. One thing to know however, is that in order to get all of the possible loot you will need 2 Punched Cards.
