Overview[]
Secret Vaults are special events where players have a chance at earning Units beyond their current level. In addition, players have the chance to earn past promo units that are no longer available, such as the Mammoth Tank. Secret Vaults were introduced in the 3.3 Patch and have made regular appearances right before Boss Strike.
The Secret Vault is available to all players that are Level 10+. Similar to Boss Strike, the event icon appears below the player's avatar with a countdown timer. When accessed, players are be able to see what units can be earned and can roll to earn these units with 
Nanopods. Players can purchase a set of 3 rolls for 180 and/or a set of 10 rolls (which provides an 11th for free) for 600.
For lower level ranges, 3 rolls cost 90 and a set of 10 rolls, as well as its free 11th roll, costs 300.
As of the 9th Secret Vault event, this changed to 1 roll for 60 or 10 rolls (which provides an 11th for free) for 600.
Each roll will provide a unit at random. The unit's value is guaranteed to match or best the player's Nanopod-spend. Depending on the player's level, different units will be made available. The level ranges were as follows:
- 10-19
- 20-29
- 30-44
- 45+
Since the 7th Secret Vault, the level ranges have been changed:
- 10-19
- 20-29
- 30-39
- 40-54
- 55+
