While exploring the stronghold of Call of Duty Warzone's new MAP Rebirth Island, you can get to the Vault Room where some quality loot awaits. To open the chests in this room, however, you will need to obtain magnetic cards otherwise known as "Vikhor's magnetic card", "Perseus' magnetic card" and "forgotten magnetic card". In this guide, we show you where you can get these three magnetic cards to be able to open the chests in the treasure room of the Rebirth Island fortress in Call of Duty Warzone.
Where to find the magnetic card of Perseus:
You'll find the first map in the "Living Quarters" area by rummaging on a shelf in a building (which we've pointed out to you on the map below). Perseus' magnetic card is the easiest to retrieve since it is very close to the fortress. By collecting it, you limit the risk of being tricked by another player when you try to get your reward. By opening the Rebirth Island fortress chest with the Perseus Keycard, you can pick up several bags of money as well as an upgraded drone.
Where to find Vikhor's magnetic card:
The second card can be found in the "Headquarters" area of Rebirth Island by going inside the bunker (location indicated on the map below). You'll find the map sitting on a desk inside the bunker. Since there is more distance between you and the fortress, you will have to be very careful not to be tricked by another player and have your magnetic card stolen on the way if you want to be able to open the chest of the middle of the treasure room with Vikhor's magnetic card. By opening the safe, you can recover a lot of money as well as an equipment drop.
Where to find the forgotten magnetic card:
The last map is a little more complicated to secure since it is at the opposite end of the fortress. You will find the forgotten magnetic card in the "Bioweapon Labs" area. When you're in the building, head into the basements and interact with the shower in the center of the room to activate it. The shower will spit out several wads of cash as well as the famous forgotten magnetic card. You will now have to find a way to cross the entire MAP of Rebirth Island to get to the fortress or this time you can open the safe on the right with your map. If you manage to open the chest with your special key, you can get a specialist bonus, an equipment drop and an ammo box.
