Avengers assemble. Updated on 27 January 2021 Assassin's Creed Valhalla has a tough achievement the game's community is now working together to help everyone unlock. You can help too, by letting yourself get killed in a specific location. The troublesome achievement, named Hall of the Slain, requires you "Avenge the death of 10 players". It's one of many awards accessible via the built-in Ubisoft Connect platform, and also one of many that suffers from bugs. In about 150 hours playing Valhalla, I've only come across the ability to avenge another player twice - and one of those times was last night while testing out the community's new method. Fans say the game's avenge system is outright broken, while Ubisoft has acknowledged in a list of known issues that "avenge quests are difficult to spot".
