About this

A Game Informer interview with Illfonic chief creative officer Jared Gerritzen covering the studio's upcoming Halloween game, a 1v4 asymmetrical multiplayer horror title that also includes a single-player Michael Myers campaign. The piece explains how the campaign ties into the 1978 film, the game's 1970s period-piece styling, and how Illfonic is expanding Haddonfield for both single-player and multiplayer.

Facts from the original

Illfonic revealed its Halloween game the week before the article was published on August 25, 2025.

Chief creative officer Jared Gerritzen calls Halloween Illfonic's biggest game yet.

Halloween features 1v4 asymmetrical multiplayer, typical of the developer.

It also includes a single-player campaign that puts players in the boots of Michael on the night of Halloween in 1963.

The single-player campaign is designed to be played first because it teaches players how to be the best Michael Myers in the game's multiplayer mode.

Players will play through the events of the first Halloween film and a little after to learn never-before-seen story about that night and acquire different abilities and perform kills on Haddonfield citizens.

Illfonic is working with John Carpenter and longtime franchise producer Malek Akkad, who has been producer since 1985 after taking over from his father, to create the game including the single-player campaign.

The game emulates the 1970s movie vibe of the original film, with Gerritzen calling it a 'period piece.'

The visual style, dialogue, and technology available in-game match the time period, applying to both single-player and multiplayer content.

Illfonic is filling out the world with NPCs and AI so heroes can save the town instead of the standard escape-alone objective.

Saving townspeople slows Michael down from killing people, and playing as Michael gives him more things to do, making the power balance more interesting than the standard genre formula.

Michael's gameplay abilities reflect his uncanny movie ability to appear anywhere and his seemingly inhuman ability to take damage.

Illfonic is working with the family of Loomis actor Donald Pleasence to use his likeness; Loomis narrates the game's campaign.

Karma: The Dark World developer Pollard Studio is helping Illfonic develop the campaign, which Gerritzen says 'supercharged' the project.

The game is developed in Unreal Engine 5.

Gerritzen describes Jason as a 'bull in a China shop,' the Predator as a 'big cat, powerful and noisy,' and Michael as a 'coiled-up cobra that happens to be in any bush you walk by.'

This is the first time the entire Illfonic team will be focused on one project.

Unreal Engine 5 allows the team to try new techniques it struggled with in the past, such as dynamic lighting.

Illfonic developed Friday the 13th, then Predator: Hunting Grounds, then had a couple of projects canceled, then worked on Ghostbusters: Spirits Unleashed before the Killer Klowns from Outer Space IP landed and Halloween arrived.

Illfonic continues to support its older titles, including releasing new Predator: Hunting Grounds content in recent weeks.

'Fun' sits at the top of Illfonic's multiplayer priorities, with 'breaking the stigma' a close second.

Gerritzen says the team 'cracked a mechanic' it has never seen in any other game, which players will experience as a 'holy s***' moment.

Halloween launches on PlayStation 5, Xbox Series X/S, and PC next year (the product listing shows a release date of September 8, 2026).

From the original

Game Informer's Wesley LeBlanc interviewed Illfonic chief creative officer Jared Gerritzen about the studio's upcoming game based on John Carpenter's Halloween, revealed a week before the article was published. Gerritzen calls it Illfonic's biggest game yet, pairing the developer's signature 1v4 asymmetrical multiplayer with a single-player campaign in which players control Michael Myers on Halloween night in 1963. The campaign is meant to be played first, because it teaches players how to be the best Michael in multiplayer, and it follows the events of the first film and a bit beyond to tell a new story. Illfonic is working with John Carpenter and franchise producer Malek Akkad to keep the game authentic, and it emulates the original film's 1970s vibe as a 'period piece,' with matching visuals, dialogue, and in-game technology. The world is filled out with NPCs and AI, letting survivors try to save Haddonfield rather than simply escape, which shifts the power balance between heroes and Michael. Michael's abilities reflect his cinematic knack for appearing anywhere and absorbing huge damage. Illfonic is also using Donald Pleasence's likeness for Dr. Loomis, the campaign narrator, with Pollard Studio helping develop the campaign in Unreal Engine 5. Gerritzen notes it is the first time the whole studio is focused on one project, describes Michael as a 'coiled-up cobra,' and says the team cracked a mechanic it has never seen in another game. Halloween is coming to PlayStation 5, Xbox Series X/S, and PC.
