World of Warcraft's cross-faction instances were announced earlier this year, and Blizzard is finally pulling the veil back a bit on the feature. In a recent post on the official site, the developers gave a quick preview of how the feature will work when it hits Shadowlands' 9.2.5 patch update.
Cross-faction instances give players the chance to dive into content together, regardless of whether they are For the Alliance or Horde. This bridges the long player divide that has helped define World of Warcraft over the years, though the lines have been mostly blurred in recent years thanks to how Shadowlands was built. The new feature will allow players to directly group together, ignoring faction loyalties, being able to instead tackle content with friends across those lines.
In order to do so, players will need to know the BattleTag or Real ID of those they are inviting to a group, or be a part of the cross-faction community in World of Warcraft. Players can join cross-faction groups, whether they are premade in the Group Finder if the group is open to cross-faction play. These groups will include dungeons, raids, Torghast, and more.
Blizzard does warn, though, that while outside the instance just because you're in a party or raid together, doesn't mean you're friendly. However, that all ends once you're actually in the dungeon, as you'll be able to help in combat, trade, and more.
Blizzard also stated that World of Warcraft's cross-faction play will include legacy instances, such as Trial of the Crusader, Siege of Boralus, Darkmaul Citadel, and more. You can check out the full list on the official forums post.
