Aniimo is multiplayer. Steam lists Single-player, Online PvP, Online Co-op and Cross-Platform Multiplayer, so you can play solo or with other people, and not only on the same platform. The most concrete mode is Egg Heist.

Solo play and Companion Mode

Steam’s feature list includes Single-player alongside Online Co-op, so the two do not conflict:

  • Solo. Nothing forces you to group up. Steam’s Single-player tag is the official confirmation.
  • Companion Mode. Once you and a friend become Companions, a link appears showing the distance between you, so you do not drift apart out in the open world. This comes from player and guide-site testing; the official help pages do not cover it on their own.
  • Story progress is tracked separately. Players report that story progress follows each account (or the host), so helping a friend does not clear it for you. The developers have not spelled this out, so trust the in-game prompts.

To play together, add each other by UID or nickname first, and make sure you are in the same region.

How Egg Heist works

The official description is specific: this is a PVEVP mode where you join a three-player team at any time and search and fight in real time in the Lost Isles. It contains three things at once:

  1. PvE: searching dangerous areas and extracting special eggs.
  2. PvP: competing with other players for the rare egg.
  3. Extraction pressure: you still have to get out with it.

It is not a co-op dungeon; cooperation and competition run side by side.

Crossplay, and what is not confirmed

  • Cross-Platform Multiplayer is confirmed: players on different platforms can play together.
  • Cross-progression is not announced. Do not assume a shared save.
  • Platform support and the Switch and Mac situation are on the platforms page.

Teaming up

  1. Agree on a time. Egg Heist needs three, and there is no published statement about matchmaking backfill.
  2. Keep a traversal slot. The Lost Isles’ terrain and search pace make movement abilities directly valuable.
  3. Split roles rather than stacking stats. The roles are DPS, Support, Heal, BREAK and Energy; a three-person team cannot cover all of them, so decide who does what.
  4. Run one round before committing. Testers reported long queues during the beta; judge the live servers after launch.

Is it an MMO?

The store genre list includes “Massively Multiplayer” and outlets describe it as an MMO. What the developers emphasise is the functional list: single-player, co-op, PvP and cross-platform multiplayer. The accurate description is an open-world RPG with multiplayer content, not a world you must stay logged into.

The loop itself is on the gameplay page and pricing is on the price page.
