Blizzard recently disclosed that Overwatch 2 has a lot of known issues. One of the problems that players are running into involves achievements. As spotted by True Achievements, players have reported that they get booted from the game and server when they unlock an achievement.

This would be frustrating enough on its own, but it's especially bad because Overwatch 2 already has lengthy queues. Unlocking an achievement--which is normally a fun and exciting thing--can be very much not that way with this issue. GameSpot experienced this bug firsthand as well. As usual, however, your mileage may vary.

Overwatch 2's achievement list is pretty much the same as the original game, with some changes, and six brand-new achievements for the sequel.
