What is confirmed

The Aniimo Steam page lists Online Co-op, Online PvP and Cross-Platform Multiplayer among its features. These tags establish the intended online modes, but they do not by themselves document every party, matchmaking or PvP rule.

For a first session with friends, use the current platform stores and in-game menus for the exact availability of each mode after launch.

  • Online co-op is listed by Steam.
  • Online PvP is listed by Steam.
  • Cross-platform multiplayer is listed by Steam.

Server choice matters

The official pre-download notice explains that same-server progress can be shared across platforms after the relevant accounts are linked. It also states that progress on different servers is independent.

That means “cross-platform multiplayer” and “cross-server progress” are different questions. Choose the same server as your friends before assuming a shared progression path.

What this page does not claim

The available sources do not establish a complete party-size limit, matchmaking queue design, PvP ruleset or every mobile-to-PC interaction. Those details should be added only after the launch client or a direct official notice verifies them.
