Overwatch players have discovered an unusual interaction that allows Symmetra to gain ultimate charge from Wrecking Ball’s ultimate.
Wrecking Ball’s ultimate ability, Minefield, deploys a field of proximity mines that explode upon coming into contact with an enemy.
As the mines are long-lasting, they must be cleared out by the opposing team if they are to reclaim the area, either by shooting them or having a hero who can take the hit simply run through them – either a Zenyatta who happens to be in transcendence, or heroes using Zarya’s protective bubble, for instance.
Symmetra’s turrets are already one of the better ways of clearing out a Minefield. While they cannot be directed at particular targets, they will default to targeting out the mines if no enemy is within reach, meaning if placed appropriately they can be used to clear Wrecking Ball’s ultimate quickly without requiring the direct attention of a player.
It seems, however, that there’s another reason for Symmetra players to prioritize targeting the Minefield. Unlike most heroes, Symmetra can earn ultimate charge by using her turrets to destroy the mines.
This interaction appears to make Symmetra the only hero in the game who can gain ultimate charge in this way. In theory, ultimate charge can only be earned by dealing damage to enemy heroes, but this seems to be the exception.
As a result, it’s very possible that this falls into the category of bug, and will likely be patched at some point in the future. In the meantime, however, Symmetra players can make the most of it by keeping an eye out for minefields, as clearing them with turrets is not only fast and effective, but also efficient for your own ultimate gain.
