Phantom Line: Prologue Is Free on 26 October – Co-op Anomaly Hunting in a Nuclear War

Phantom Line Prologue launches for free on Steam on 26 October 2026. It's the first playable chapter of Phantom Line, a 1–4 player co-op tactical shooter from Antistatic Studios that mixes military combat with paranormal horror in a Europe tearing itself apart in a nuclear war.

If you liked GTFO, Ready or Not or Gray Zone Warfare and wished they had monsters from another dimension, this one is worth a look. Here's the release date, what's in the Prologue, how the H.U.S.K. body-swap system works, PC requirements and what we know about the full game.

Phantom Line: Prologue at a glance

When is the Phantom Line Prologue release date?

Antistatic confirmed on 29 September that the Prologue launches on 26 October 2026, and repeated the date in its October devlog: "26 October. Report for duty, Operators." No launch time has been shared yet. It has its own Steam page, separate from the full game, so you can add it to your library on the day without buying anything.

Is Phantom Line: Prologue free?

Yes. Antistatic says the Prologue launches "completely free". It's an introductory chapter that offers "a glimpse of the bigger experience" the studio is building, not the whole game.

What is Phantom Line about?

You play an Operator in an elite special-ops unit that deals with anomalies, bizarre events hidden from the public, for a mysterious megacorp called Mortfield Industries. One of Mortfield's research sites in the Iron Corridor, an Eastern European region already torn by international tension and paranormal activity, has gone silent. You're sent to investigate just as nuclear war breaks out.

So your squad is fighting on two fronts: tears in space-time and monstrous entities on one side, and a full-blown human conflict on the other. Antistatic describes Phantom Line as a dedicated PvE game: no player-versus-player.

What's in Phantom Line: Prologue?

From Antistatic's launch announcement, the Prologue includes:

• Operator training to learn the basics.
• Your first story mission, deploying to an island to investigate anomalies for Mortfield.
• Reaching the ship, your base of operations (the full game describes it as a nuclear-powered icebreaker).
• A chance to explore some of the open-world systems on the introductory island and start working out what happened there.

The full open world and progression come later. Antistatic says movement, performance, UI and localisation are still being refined and asks players to send reports from this "deployment".

How does the H.U.S.K. system work?

H.U.S.K. is Mortfield's Operator Simulation Program, and it's the game's big idea. You transfer your consciousness between artificial bodies, so death is a setback, not the end. Antistatic suggests using bodies to scout dangerous zones, distract or decoy enemies, flank anomalies or even sacrifice a body to secure a target.

Containing anomalies gives you Quintessence, a substance you use to upgrade your bodies, abilities and gear. The studio's tagline sums it up: "to fight the anomalous horror you must turn into one yourself."

Can you play Phantom Line solo?

Yes. It's built for squads of 1–4 players, with online and LAN co-op listed on Steam, but Antistatic says you can go solo and use the H.U.S.K. system to manage the risk.

What changed since the March playtest?

Thousands of players joined Phantom Line's March playtest. In Devlog #4, "From March to Prologue", co-founder Maciej explains how that feedback shaped the Prologue, including the length of the tutorial, movement, combat and how clearly the game shows what's happening around you.

Phantom Line: Prologue PC requirements

DirectX 12 and a broadband connection are required. The Steam page warns of intense violence, blood, horror themes and mature story themes, including conspiracy theories.

Is Phantom Line coming to PS5 or Xbox?

No console versions have been announced. Both the Prologue and the full game are listed for PC on Steam only.

When does the full Phantom Line release?

The full game's Steam page lists 2027, with no exact date. The final game adds a full open world in the Iron Corridor with dynamic events and weather, hostile factions, base upgrades on your icebreaker, crafting, recruiting crew and deeper progression. Your assignment "will continue in the full game", Antistatic says. You can wishlist Phantom Line to follow it.
