Credit Booster doubles the amount of credits earned from pickups and mission rewards. Set in the far reaches of outer space during a new Dark Age, WARFRAME introduces the Tenno, a race on the brink of extinction after being enslaved by the Grineer for centuries. Players enter WARFRAME on the cusp of the Grineer's victory over the Tenno until they begin to arm themselves with WARFRAMES - an ancient exo-skeletal technology only they can operate. Hidden within the Orokin Derelicts of a lost civilization, new WARFRAMES lie dormant and undiscovered. These artifacts are the Tenno's only hope for survival.
