Overview

CATENA - Chapter I is a free-to-play action-adventure from developer and publisher Mouseworks, released on November 3, 2026. It's designed as an asymmetric couch co-op experience, meaning two players share the screen but not the same role.

The game's premise is as striking as its mechanics: a rift has torn reality apart, and the sorcerer TABES attacks both the Physical Realm and the Astral Plane simultaneously. To counter this dual threat, the echo CATENA splits her body in two, and the two halves are bound by a chain.

This isn't just a narrative flourish—it's the core of the gameplay.

Highlights

  • Asymmetric Combat: The two Catena halves play differently. The Physical Catena (Player 1) is described as pure will to live, courage, and near-naive optimism, matching the brutal rhythm of the real world. The Astral Catena (Player 2) embodies her suppressed fears—cynical, pessimistic, questioning every step. This contrast isn't just flavor; it likely affects how each character handles combat and traversal.
  • Shared Life Pool and Weapon: Both players share one life pool and one weapon. This creates a tense, cooperative dynamic where every hit taken by either player affects both. Coordination is essential, and the chain that binds them visually reinforces this interdependence.
  • Co-op Modes: The game supports Multi-player, Co-op, and Shared/Split Screen Co-op, making it a perfect couch co-op title. It's free to play, so there's no barrier to trying it out with a friend.

Who It's For

If you enjoy couch co-op games that demand real teamwork, or if you're drawn to action-adventures with a strong narrative hook, CATENA - Chapter I is worth a look. The asymmetric design means each player has a distinct experience, which can be refreshing for duos who are tired of mirror-symmetric co-op.

The game's atmospheric, stylized 3D visuals and hack-and-slash elements also appeal to fans of action games. Since it's free to play, it's easy to jump in and see if the dynamic clicks for you and your partner.
