Expansion history
The original ArcheAge received major content updates throughout its 12-year lifespan. These are listed with their Western (NA/EU) launch dates where available. Korean servers typically received updates 3-6 months earlier.
Conquest of Auroria (1.7) - November 4, 2014
The first major content expansion opened the entire Auroria continent. Guilds could claim territories, build castles, and engage in siege warfare for political and economic control. The four claimable territories (Nuimari, Calmlands, Heedmar, and Marcala) became the endgame's focal point. This update also introduced Diamond Shores as the gateway zone.

Heroes Awaken (2.0) - September 12, 2015
A major systems overhaul that added the political system allowing players to take up leadership roles on servers. Included upgraded crafting houses, guild expeditions, guild wars, and server evolution that merged and restructured existing servers.
Revelation (3.0) - December 10, 2016
One of the largest expansions. Added two new playable races: Dwarves (Nuia Alliance) and Warborn (Haranya Alliance), each with unique racial transformation abilities. Introduced Magithopters (hovering aerial vehicles), the Abyssal Skill system for deeper skill customization, and new zones Airain Rock and Sunbite Wilds.
Legends Return (4.0) - 2017
Added the Swiftblade skillset, the 10th base skillset focusing on fast dual-wield melee combat. This brought the total class combinations to 165 (from the original 120). Also included quality-of-life improvements and new content zones.

Relics of Hiram (5.0) - November 2018
Originally targeted for October 24, 2018, the launch was delayed three weeks due to the Gamigo acquisition of Trion Worlds. The expansion added the Malediction skillset (11th skillset, 45 new class combinations using dark magic), the Western Hiram Mountains zone, and the Hiram gear system that transformed endgame itemization by providing a deterministic upgrade path.
Shadows Revealed / Unchained (6.0) - October 15, 2019
This update coincided with the launch of ArcheAge: Unchained, the buy-to-play version. Both the free-to-play and Unchained versions received the Shadows Revealed content update, which included new dungeons, the Swiftblade skillset improvements, and additional Auroria content.
Garden of the Gods (7.0) - June 2020
A major expansion that continued the game's evolution with new systems, content, and story progression.

Spelldance (8.0) - Late era
Added the Spelldance skillset, the 12th and final skillset. Based on the lore of Naima, one of the twelve heroes who died during the expedition, the skillset featured dance-based healing abilities. This brought the total class combinations to 220.
Final updates (2021-2025)
Under Kakao Games' publishing, the game received additional content patches focused on balance adjustments, quality-of-life features, and the eventual merger of ArcheAge and Unchained in December 2023. Development resources increasingly shifted toward ArcheAge Chronicles as the original game wound down toward its March 2025 closure.
