How is the Keyvault working?

Keyvaults (containers) spawn at certain positions on the map. To get into these you need a keycard. There are 6 different keyvaults, and therefore also keycards. Each level (Zeta to Alpha) results in better loot. The keyvault can only be opened once per server period.

The following drops appear in Keyvaults:
- Rubber Ducks (2 * level)
- Vehicle crafting items (5 * level)
- Money (12500 * level)
- Weapons (only one weapon per vault and a couple of random magazines)
- Special clothing (only one item per Vault)
