The last time Age of Mythology: Retold received a major expansion, Tale of the Dragon dropped a full Chinese pantheon onto a game that critics had already called one of the most faithful remasters of the last decade. Today, World's Edge returns with something substantially larger. Obsidian Mirror, launching April 21, 2026 across Steam, Xbox, Game Pass, and PlayStation 5, is the biggest content drop Retold has ever received, and it is the one moment most of the Age of Mythology community has been waiting for since the remaster first shipped in 2024. The Aztecs are finally here.
This is not a small DLC. Obsidian Mirror arrives with three new Major Gods, nine new Minor Gods, a brand-new 12-mission campaign, an entirely new mechanical system built around sacrifice and fear, and a cosmetic and balance pass that touches nearly every existing civilization in the game. World's Edge, Forgotten Empires, Tantalus Media, CaptureAge, and Virtuos have been working on this for over a year, and the final product looks like the most mechanically ambitious expansion the series has ever shipped.
The trailer above gives a strong first impression of what the Aztec pantheon brings to the battlefield. Blood-slick pyramids, obsidian-tipped spears catching moonlight, and jaguar warriors tearing through formations that would have held firm against a Greek phalanx. But the real story is in the mechanics, because the Aztecs play unlike any civilization Retold has ever shipped with.
Three Major Gods, Nine Minor Deities, and a Pantheon Built on Fear
Players choosing the Aztec civilization will pick from three Major Gods at the start of a match, and each one encourages a fundamentally different playstyle. Quetzalcoatl, the Feathered Serpent, is the trade and diplomacy god, offering cheaper market costs and passive villager bonuses designed for players who like to sim hard and snowball through economy. Tezcatlipoca, the Smoking Mirror, is built around deception, scrying, and psychological disruption, with godly powers that let you see through enemy fog of war and sow confusion among opposing units. And Huitzilopochtli, the Sun and War god, is the straight-aggression pick, built for players who want to push spearmen and jaguar warriors into enemy cities before their opponent finishes their second age.
Each Major God unlocks three Minor Gods across the Classical, Heroic, and Mythic ages, giving you nine total deities per campaign. These include familiar names like Tlaloc (rain and agriculture), Xipe Totec (the Flayed One, god of regrowth), and Mictlantecuhtli (lord of the dead), but the surprise is how mechanically distinct each one feels. World's Edge has clearly studied what made Retold's existing Minor God system work and pushed it further. Where Greek Minor Gods often feel like simple unlock trees, Aztec Minor Gods restructure how you think about your entire economy.
The Tonalli System Turns Blood Into Power
The Aztec mechanical identity is built around a new resource called Tonalli, translated in-game as life force. You earn Tonalli by killing enemy units, completing rituals at your temples, and, crucially, by sacrificing your own villagers and mythic units. Spending Tonalli unlocks god powers, empowers specific units for short windows, and activates devastating map-wide effects that no other civilization in Retold can replicate.
The sacrifice mechanic is the most interesting wrinkle. Most RTS players have been trained for decades to protect their villagers at all costs. Losing villagers is losing eco. Obsidian Mirror flips that. Late-game Aztec play rewards deliberate villager sacrifice, trading economic tempo for explosive on-demand power spikes. You can feed a dozen workers to a pyramid, generate enough Tonalli to call down a godly cataclysm, and end a game in a single exchange. The obvious risk is that you arrive at the late game with nothing left if the push fails.
Alongside Tonalli, Obsidian Mirror introduces a fear and illusion layer that affects enemy behavior on the battlefield. Certain Aztec units carry a fear aura that reduces the attack speed of nearby opposing units, and several Minor God powers let you spawn illusions, temporarily turn enemy units against their allies, or build what the studio calls skull towers, defensive structures constructed from the corpses of fallen enemies. It is mechanically weird. It is also exactly the kind of asymmetric design Age of Mythology has historically done better than any other RTS on the market.
A 12-Mission Campaign That Spans Continents
The headline feature for single-player fans is the new Obsidian Mirror campaign, a 12-mission narrative that World's Edge has been hyping as the longest and most cinematic story content the series has shipped since the original Titans expansion back in 2003. The campaign follows the fall of the mythic city of Aztlan, the ancestral homeland of the Aztec people, as sibling deities wage a continent-spanning war that drags the Greek and Norse pantheons into the conflict.
Early hands-on impressions from outlets that received review copies describe the campaign as significantly more ambitious than Retold's base-game campaigns in both scope and mission variety. Players cross oceans, recruit legendary heroes from rival pantheons, and in at least two missions play from the perspective of the Aztec gods themselves rather than their mortal followers. It is a structure that Age of Mythology has experimented with before, but Obsidian Mirror leans into it harder than any previous entry in the franchise.
Pricing, Pass, and Platform Launch Notes
Obsidian Mirror is available as a standalone DLC for $14.99 on Steam, Xbox, and PlayStation 5, and it is included for Expansion Pass owners at no additional cost. Xbox Game Pass subscribers get the expansion included with their subscription starting today. The update is rolling out in waves across regions, with the Steam version live first and console versions following within the next few hours.
Alongside the paid expansion, World's Edge is shipping a free update for all Retold players that includes balance passes on the existing nine civilizations, a new ranked season, and a set of quality-of-life improvements to the map editor. The studio has also confirmed that Obsidian Mirror is the first of at least two paid expansions planned for 2026, with the next expansion rumored to add the Celtic pantheon later in the year.
For a game that launched in 2024 to a warm but mixed reception, Retold has quietly built one of the most dedicated post-launch communities in the RTS space. Obsidian Mirror feels like the moment the remaster completes its transformation from faithful restoration into something genuinely new. The Aztecs have been the most requested civilization in the Age of Mythology community for over twenty years. Today, they finally arrive.
