🥊 Poly Fighter hits Steam Early Access on October 13, and there’s a free demo you can play right now. HeartLoop Games’ single-player roguelike fighter is also on the floor at PAX West through September 7 — so if you’re in Seattle this weekend, you can get hands on it today.
⚖️ A Fighting Game With Nobody to Fight
This is the pitch, and it’s aimed at a problem the genre has never really solved.
Fighting games have extraordinary depth, and almost all of it sits behind a wall — you learn by being comprehensively beaten up by strangers online until something clicks. Enormous numbers of people love watching fighting games and bounce straight off playing them.
Poly Fighter’s answer is to remove the other person entirely. No ranked ladders. No online. No matchmaking. Just 1v1 arcade duels against AI opponents, structured as a roguelike run through an underground league.
And the way you learn a moveset is by taking it off the people who beat you with it.
Fight. Adapt. Overcome.
Every opponent you put down hands over one of their moves. Fifteen fights later you’re a Frankenstein of everyone who ever hit you.
Montreal-based HeartLoop Games has announced that its debut title Poly Fighter arrives in Steam Early Access on October 13, 2026. The single-player roguelike fighting game blends fast one-on-one combat with run-based progression, built as an explicit love letter to arcade classics.
The announcement lands alongside a new trailer and, more usefully, a free online demo available now. The game is also playable at PAX West from September 4 to 7, which is happening as we publish.
Stealing Moves Is the Whole Idea
🥋 Your Moveset Is Loot
Defeat an opponent and you earn one of their abilities. Then you swap, chain and upgrade what you’ve collected, building synergies as the run goes on.
It’s a smart translation of roguelike design into a genre that has never used it. In a normal fighting game your character’s moveset is fixed and mastery means learning it deeply. Here, the moveset is the run — you’re assembling a fighter out of whatever the league throws at you, and the same character can end up playing completely differently two attempts running.
Crucially it also teaches by acquisition. You don’t read a frame data spreadsheet to learn what a move does; you get hit by it, then you take it.
🛡️ Super-Armoured Tank
Walk through hits and make them regret standing close. Slow, punishing, immovable.
💨 Rushdown
Relentless forward pressure that never lets the opponent breathe or reset.
📏 Zoning Specialist
Control space, dictate distance, and punish anyone who tries to close it.
🎆 Projectile Chaos
Fill the screen with nonsense until something connects. HeartLoop’s own description.
🎮 Modern Controls or Motion Inputs — Your Call
The other accessibility decision worth flagging: you can choose between modern, approachable controls and nostalgic motion inputs.
That’s now standard in the genre’s biggest releases, and it’s the right call for a game explicitly courting people who’ve never played a fighter. HeartLoop’s framing is that combos should be easy to pick up while the thousands of possible move interactions provide the depth.
Whether the simple scheme stays expressive enough for veterans is the question a demo answers better than a press release — and there is, conveniently, a demo.
What the Store Page Adds
🏆 Structure Beyond the Announcement
A few details on the Steam listing that the release doesn’t cover:
• Three leagues to rise through, plus ascension runs and secret boss fights for anyone who clears them
• A large cast of unlockable playable characters, each with unique perks — so builds vary by starting fighter as well as by what you steal
• A “Deep Discovery Loop” governing how those characters are unlocked
• Alongside the demo, there’s a playtest you can request access to directly on the Steam page
• The store page carries an awards badge, though the specific award isn’t named in text
Combined, that’s a meaningfully clearer picture of the endgame than “climb the ranks” — there’s a completion structure here, not just an endless ladder.
It’s Already Turned Heads
Worth knowing that this isn’t a cold announcement. Poly Fighter drew notable coverage out of PAX East earlier in its development, picking up write-ups from Kotaku, The Escapist and Creative Bloq — with the recurring theme across all three being that it’s the fighting game for people who don’t play fighting games, and that the low-poly nineties presentation is doing a lot of the heavy lifting.
For a self-published debut from a new studio, that’s genuine traction, and it’s presumably why HeartLoop are putting it in front of people at a second major show rather than going quiet until launch.
How to Play It
🖥️ Demo Now, Early Access October 13
Poly Fighter is PC-only via Steam with no console versions announced and no price given. The free demo is live now, and there’s a separate playtest sign-up on the store page if you want deeper access.
It’s single-player only — no co-op, no versus, by design — with English voice audio and interface, plus French interface and subtitles. Fitting for a Montreal studio.
The listed minimum spec is Windows 10 64-bit, an Intel i5 12th gen, 8 GB of RAM, an RTX 2060 or RX 5700, and 10 GB of storage. That’s a surprisingly modern floor for a deliberately low-poly retro fighter — worth checking before you commit. No recommended tier is listed, and the Steam page still shows the release as simply “2026,” so expect it to firm up to the announced date shortly.
If you’re at PAX West, it’s on the show floor through Sunday.

Who’s Making It
🇨🇦 HeartLoop Games — Montreal, Canada
A new independent studio founded, in their own words, by a bunch of old friends who still get excited about making cool stuff together. Their stated approach is to build in steps, share early with players, and stay flexible enough that the game can evolve — which is about as honest a description of why a studio goes Early Access as you’ll read in a press release.
🗣️ Osama Dorias — Creative Director, HeartLoop Games
“We’re excited to finally share that Poly Fighter is coming to Early Access on October 13 as we’re keen to get the community’s input on the game. PAX West is a great opportunity for us to put the game directly into players’ and press’ hands.”
Poly Fighter hits Steam Early Access on October 13, 2026. The demo is available now, and it’s playable at PAX West through September 7.
