Fight, evolve, and experiment in Poly Fighter’s latest demo from June 15 until June 22
Montreal, Canada – 9 June, 2026 – Independent Montreal-based studio HeartLoop Games is excited to announce that its debut title Poly Fighter will be part of Steam Next Fest from June 15 – 22 with a brand-new demo. Players around the world will be able to jump into the game’s unique blend of retro-inspired fighting action and roguelike progression during the week-long event.
Developed as a love letter to fighting games and arcade classics, Poly Fighter combines fast-paced one-on-one combat with run-based progression, allowing players to steal moves from defeated opponents and create wildly different builds every run. Whether building an unstoppable tank, a relentless rushdown fighter, or a projectile-heavy chaos machine, players are encouraged to experiment with powerful move combinations and evolving strategies.
During Steam Next Fest, players will get an early taste of the over 40 unlockable characters, each with their own moves, playstyles, and strategic possibilities through a brand-new demo featuring 2 starter characters and 2 additional unlockable characters.
The demo will also feature new kick-ass moves, gameplay nodes (including Bonus Stages!), combat improvements, and a fresh opportunity for players to experience Poly Fighter ahead of launch. Players can wishlist the game, try the latest demo throughout the event, and provide feedback directly to the developers by joining the Discord community.
Poly Fighter is currently in development for PC and will be playable during Steam Next Fest from June 15 – 22. Players can wishlist the game and download the demo on Steam.
About HeartLoop Games
HeartLoop is an exciting new indie studio based in Montreal, Canada and founded by a bunch of old friends who still get excited about making cool stuff together. We love games: playing them, talking about them, and especially creating them. Our approach is simple: build things step-by-step, share them with players early, and stay flexible so the game can evolve into the best version of itself. Most of all, we are making Poly Fighter because it is the kind of game we would love to play ourselves. Montreal can be a very cold place, but we are very warm people.
