About CHAINSPIRE
CHAINSPIRE is a co-op soulslike platformer for 1-4 players in which the party is bound by a fully simulated physical chain. Combat, platforming and puzzles - all of it is built around that piece of iron. It brings together challenging combat and bosses like in Dark Souls and Elden Ring, and a shared chain that ties the fate of the whole party together like in Chained Together.
CO-OP AND THE CHAIN
Your friend becomes your enemy the moment they stop listening to you. The chain here is the real thing: it catches on geometry, goes taut, and drags back whoever wasn't paying attention. The difficulty climbs steadily as you go, and the bigger the party, the harder it gets for everyone in it.
CUSTOMIZATION CHARACTER
Make your character your own. Customize the colors of their clothing and armor, combining different shades to create a look that stands out.
BOSSES
Every boss is unique and comes with its own attacks. You learn each of them separately, and nobody gets one on the first run.
AI COMPANION
Co-op is optional. If you have no one to play with, or you'd rather make the climb alone, an AI companion takes the other end of the chain. It follows your route, fights alongside you and turns up where a second pair of hands is needed. Solo is a full mode, not a concession: the chain is still there, and so are all of its rules.
CLASS SYSTEM
Pick the class that suits you and your party: swordsman, archer and mage. Each has its own strengths and weaknesses. Your job is to balance the party: on a single chain, what matters isn't only who you are, but who's holding the other end.
A DARK, BRUTAL WORLD
The way up starts in damp dungeons and runs through halls, galleries and bridges that show you exactly how far you've climbed and how long the fall would be. Nothing here lights your path: look around, climb where you probably shouldn't, and take everything you find.
The game will be released a few months after the release of GTA VI.
