When Onslaught first launched in Destiny 2 with the Into the Light update on April 9, players quickly discovered that batteries meant to heal the ADU could also be thrown at and heal damaged defenses. The bug officially became a feature after the weekly reset on April 30.

“This week we made some changes to how ADU batteries work in Onslaught. While we were working to fix a bug where batteries could heal defenses, we decided to keep healing with a few balance adjustments: we improved the healing factor and made healing consume battery,” the Destiny 2 developer shared on May 1.

According to the developer, this bug was an interesting mechanic and something worth analyzing as a permanent addition to the game mode. From a player perspective, many also felt that this bug should be a core part of Onslaught, as they didn’t want to lose all the scrap invested in a maxed-out lure just because a Tormentor decided to show up.

The developer added that this was also a case of making Onslaught's Legend difficulty non-trivial. Difficulty should matter in Legend level activities, and now there's an additional strategic element to the game mode.
