Get forever perks for your character
The Tiered VIP system offers game perks which are forever linked to your character. Each VIP level brings new elements you can take advantage of in your adventures. Your VIP level is also visible to all other players.
VIP 1: Get a bigger backpack when scavenging
VIP 2: VIP 1 Perks + Auto Play while scavenging (be careful to only use it in zones where you feel relatively safe)
VIP 3: VIP 2 Perks + a Turret in the defend the city game mode
You can either accumulate VIP points at different places in the game until you get enough to exchange them for a VIP level. Or you can purchase one VIP level for a direct purchase.
