Rhino Prime's devastating offensive attacks and formative defensive powers make him the cornerstone of any squad, and strong enough to survive alone. Pair him with the Boltor Prime -- a great rifle for close to medium-range targets -- or the Ankyros Prime’s high attack speeds and you've got high-powered crowd control.
On February 16, Rhino Prime, Boltor Prime and Ankyros Prime will enter the Prime Vault, with all of their crafting parts abolished from The Void. If you already wield the power of these Primes, they will remain in your inventory.
The Prime Vault will house these Prime items until they return, but they will be out of reach to Tenno in the meantime.
Tenno, this week is your last chance to enter the Void to collect and craft these items. Be sure to take advantage!
