Manibus is Once Human's introductory PvE scenario. In this scenario, players need to work together to complete server-wide quests like Prime Wars and defeat difficult overworld bosses such as Manibus itself.
While it's tagged as a PvE scenario, certain public events like the Cargo Scramble will force you in PvP mode where you have to compete with other players for some resources. If you want a collaborative gaming experience with just the right amount of challenge while exploring, the Manibus scenario is one for you!
Normal and Hard difficuly Manibus servers were introduced last August 20, 2024. These servers feature super anomalies, shiny deviations with special abilities, new cradle overrides, better rewards, more prize pool blueprints at the Wish Machine, new calibration blueprints, and more polluted zones with increased contamination levels.
If Manibus (Novice) is too easy for you, we recommend signing up for some of the Normal and Hard difficulty servers for an added challenge.

Evolution's Call is Once Human's introductory PvP scenario. In this scenario, players compete with each other for resources. You aren't always in PvP mode in this scenario though. You'll only enter PvP mode by toggling Chaos State and doing so enables you to fight against other players who are also in their Chaos State.
Evolution's Call also feature territory wars and echo stone purifications. If you love the thrill of fighting against other players, then Evolution's Call is the right scenario for you.

Normal and Hard difficulty servers were also introduced for Evolution's Call late in August. Just like with the Manibus Normal and Hard difficulty servers, these new Evolution's Call servers also feature super anomalies, shiny deviations, new cradle overrides, better rewards, more prize pool blueprints at the Wish Machine, new calibration blueprints, and more polluted zones with increased contamination levels.

Prismverse's Clash is a PvP scenario that was launched last September 26, 2024. It features a faction war between the Mayflies and the Rosetta where each faction needs to secure prism deviations.
It uses the same map as Manibus and Evolution's Call but this time with safe and war zones. Players will only enter PvP mode when they're in the war zones.Prismverse's Clash only has 4 phases and the entire scenario spans for a total of 19 days.

Endless Dream is a scenario that was released on July 2, 2025, but was released as an early access back in May 21, 2025. Players will have to take on the Dream Zones that terrorize the world and save it from its absolute destruction.

Deviation SCP is the latest early access scenario that was released on September 25, 2025. It has a high chance of fully releasing on October 30, 2025 during the Palworld x Once Human collab event!
The players' main goal is to capture and nurture the best deviation and become the best handler in the scenario. They can battle the NPCs (Gyms) or matchmake to fight other players to test their strength.

In Once Human, a Scenario is used to describe the gameplay theme that the game's PvP and PvE servers have to offer. The PvP Scenario Evolution's Call, and the PvE Scenario Manibus are examples of these themes.

A Scenario's progression and timeframe happens in accordance to the Season length it is given. Different Scenarios will have different Season lengths, and in-game content is unlocked as the Season progresses.

Different Scenarios will have different content and gameplay experiences to offer the player.
Some Scenarios may focus on exploring and collecting Deviants, while others have the player working against other Meta-Humans for survival. There may also be new mechanics, maps, and enemies for players to experience.

After the Season ends, the server will enter what we call the Settlement Phase, wherein all content has been unlocked and players can continue enjoying the Scenario for a little longer.
For the Evolution's Call and Manibus Scenarios, the Settlement Phase has a duration of 4 Weeks. Afterwards, the server will close, and players' characters and applicable items will be sent to Eternaland.

Once the Season reaches its last stage, players can opt to sign up for a new Scenario. This will begin a new journey for players, and those that had their characters sent to Eternaland can also choose to join a new Scenario at any point.

Certain things are retained after a Season and Scenario ends. The created character, important items and currencies, cosmetics, friends, Battle Pass and task progress, and furniture formulas will be retained when changing scenarios.
Weapon and Armor related items, such as Blueprints and Mods, Food Recipes, House Blueprints, and Furniture Formulas are retained as well. Items like Deviants, regular resources, and crafted gear will be sent to Eternaland.
How to Prepare For Season Reset

Not everything is retained, unfortunately. A Character's level and their Memetics-related attributes will be reset to ensure that new and veteran players start on equal footing in a new Scenario.

Players will be given a limited amount of Resource Points which can be used to export items from Eternaland to the current season. These points are refreshed everytime a player joins a new scenario.
