All Once Human Phases, explained

Phases in Once Human are part of Starry Studio's ambitious and controversial Seasonal Scenario system, inspired by the season mechanics from ARPGs like Path of Exile, Last Epoch, and Diablo 4. The developer plans to soft-reset players' progress after Season 1, introducing entirely new maps, story quests, and gameplay content, making it challenging to predict how the second season will integrate its phases.

Even in Season 1, there's ambiguity about what Phase 6 (final phase of this season) will comprise, as the game is currently in Phase 4, with information available only up to Phase 5.

This guide covers everything you need to know about phases in the first Seasonal Scenario of Once Human up to Phase 5.

What are Phases in Once Human?

There are six phases in the first Seasonal Scenario of Once Human. Each phase unlocks new content, including map regions, Silos, Monoliths, Prime Wars, Public Crisis Events, and harder difficulty modes.

Instead of unlocking all at once like in ARPGs, content in Once Human is unlocked progressively to prevent players from rushing through activities to reach the endgame quickly.

The developer confirmed that the first Seasonal Scenario will be six weeks long. So, players initially assumed that each phase would last one week, which was true for the first three phases. However, the ongoing Phase 4 is ten days long.

The developer also confirmed that Seasonal Scenarios can vary in length. While Seasons 1 and 2 will be six weeks long, Season 3 and beyond could be longer or shorter, making the length and number of phases in each season variable.
