History of Onslaught

Onslaught is a wave-based defence activity for one to three Guardians, defending an Advanced Defense Unit (ADU) against waves. It launched with Season of the Wish as a playlist activity with Normal and Legend tiers; 50 waves earns maximum rewards. Players earn Scrap to buy and upgrade defences; wave types include bonus, augment, rift and boss waves. Rewards include BRAVE Arsenal weapons. The later Onslaught: Salvation variant of Episode: Revenant adds a 10-wave mode and new defences. Not to be confused with the Onslaught weapon perk, which raises rate of fire with Rampage.
