CATENA - Chapter I
Mouseworks
CATENA is a co-op action-adventure about two players chained together, sharing one body, one life pool, and one weapon. Toss the blade to swap roles and battle mirrored enemies across two realms as one.
Overview
One body divided. Two players united.
An asymmetric couch co-op where survival means working as one.
A massive rift has torn reality apart. The sorcerer TABES strikes on two fronts at once: the Physical Realm and the Astral Plane. To fight back, the echo CATENA splits her body in two. Bound by a chain, both players share one life pool and one weapon.
Choose your character:
🎮 The Physical Catena (Player 1): pure will to live, courage, near-naive optimism. She matches the brutal rhythm of the real world.
🎮 The Astral Catena (Player 2): the sum of her suppressed fears. Cynical, pessimistic, questions every step.
Core Gameplay
⚔️ Asymmetric Combat
Armored husks only take damage in the real world / spirits must be banished on the astral plane. Fight mirrored enemy hordes together - every hit demands coordination.
🔄 The Weapon Toss
Toss the single sword between players to swap roles instantly: one fights with melee combos, the other protects with tactical wind control.
🏄 Windsurfing & Platforming
Slide at high speed across open fields and time your jumps on crumbling rocks.
🗿 Runestones
Activate ancient, humming stones for a lasting healing aura - your anchor point mid-fight.
Explore Ktonia
Step out of the cave into a vast, wind-swept world where the ancestors speak through runestones.
Loot with Impact
Fallen enemies drop powerful boosts: Shield, Time Slow, and Score Multiplier.
