Horde or Alliance: which side do you fight for? That allegiance will be put to the test in latest World of Warcraft expansion, Battle for Azeroth.

Announced during the opening ceremony at this year’s Blizzcon with a stunning cinematic trailer, Battle for Azeroth focuses on the classic conflict at the heart of the MMORPG. Players will venture to the regions of Kul’Tiras and Zandalar to fight for their faction in new dungeons, raids and global events.

One of the expansion’s new features, Island Expeditions, sends players to uncharted isles to gather a resource called Azerite in 3v3 PvE or PvP skirmishes. Each island is randomly generated so while your objective is the same each time, the obstacles in your way can vary with each visit.

Players will also be able to reach a new level cap of 120, recruit allied races to their side and take part in large-scale 20-player Warfronts.

World of Warcraft: Battle for Azeroth will be released in 2018.
