Prime Vault

The Prime Vault, an archive outside of Tenno reach, houses items that have been retired from the game's reward tables. "An item enters the Prime Vault" means that players are no longer able to obtain new copies of that item from the game. Preexisting copies of the items will remain in players' inventories and can be traded.

Items in the Prime Vault can be reacquired in limited-time Prime Vault Packages which offer retired Prime items and Prime Access-exclusive accessories. Prime weapon and Warframe parts included in the package will also become available from Void Relics during the duration that the package is up for purchase.

Mag Prime Vault
The Mag Prime Vault was available from June 28 to July 26, 2016.

Frost Prime Vault
The Frost Prime Vault was available from December 8, 2015, to January 5, 2016.
