Halloween: The Game Developer and Publisher: IllFonic and Gun Interactive

Who developed Halloween: The Game?

IllFonic. Two separate places say it in almost the same words. The Steam store data record for this product lists developers: ["IllFonic"], and the footer of the official site states:

Game software excluding Compass International Pictures, Inc. elements: ©2025 IllFonic, Inc. All Rights Reserved. Developed by IllFonic, Inc.

A third, smaller confirmation sits in the support fields: the only support mailbox either source publishes is [email protected], and the official site’s own production posts speak as the studio — a September 2025 post on making the announce trailer quotes “Jared Gerritzen, Head Designer at IllFonic” describing what “our in-house development team” turned around in-game.

Last verified: September 22, 2026.

Who publishes the game, and who is the co-publisher?

The Steam record’s publishers array holds exactly two strings, quoted verbatim:

That is the whole published picture of the publishing side, so read it narrowly. The official site’s footer adds a third name in a different register — ”© 2025 Gun Media Holdings, Inc. All Rights Reserved. Gun Media™ and the Gun Media™ logo are trademarks and/or registered trademarks of Gun Media Holdings, Inc. throughout the world.” — and Gun Interactive’s own site, which the game site links directly, keeps a company footer reading ”© 2023 Gun Media Holdings, Inc.” The two pages never spell out how the two Gun names relate, and neither does this page.

One useful cross-check: on the co-publisher’s own site, the Halloween page’s footer carries the same “Developed by IllFonic, Inc.” line as the game site does. Both parties’ pages credit development to IllFonic.

Where is IllFonic based?

The studio’s own home page states it twice, in consecutive sentences:

IllFonic is an independent video game studio located in Colorado and Washington. Founded in 2007, IllFonic is an independent video game developer with studios in Lakewood, Colorado and Tacoma, Washington.

So: independent, not a subsidiary described as such on these pages; founded in 2007; two named US locations, Lakewood, Colorado and Tacoma, Washington. The studio’s site does not say which of the two offices worked on this game, and this page does not guess. If you want the rights holder’s location rather than the developer’s, the official game site links Compass International Pictures’ own page, which lists an address at 2021 Pontius Avenue, Los Angeles, California.

What else has the studio made?

IllFonic’s home page introduces its back catalogue in one sentence, quoted in full:

Titles and collaborations include Killer Klowns From Outer Space: The Game, Ghostbusters: Spirits Unleashed, Arcadegeddon, Predator: Hunting Grounds, Friday the 13th: The Game, Dead Alliance, Star Citizen, Evolve, Armored Warfare, and Nexuiz.

Treat that list the way it is written. The studio’s own wording is “titles and collaborations”, which is a wider category than “games we developed” — the sentence itself does not sort which entries the studio led and which it supported, so no reading of it should claim that it did.

Two things worth noticing about this list in relation to the game you are actually looking for. First, the two titles readers keep asking about are both in it: Friday the 13th: The Game and Killer Klowns From Outer Space: The Game are named in that sentence, and Killer Klowns also gets its own live site linked from the studio’s game cards. That is the whole basis of the “same developers” question, and it is a studio-level fact, not a personnel one. Second, Halloween: The Game is not named in that sentence, even though the same page’s game cards link straight to halloweengame.com. The prose list and the card grid are different blocks of the same site, and this page quotes each as it stands rather than merging them.

Is it the same team behind Friday the 13th and Killer Klowns?

At studio level, yes — on the studio’s own account. Both titles are named in the “Titles and collaborations include” sentence above, so the entity that lists them is the same entity the Steam record names as developer of this game.

Where the claim stops: none of the sources used here says that the people who worked on those projects moved onto this one, and no staffing or team-continuity information is published. “Same studio” is documented. “Same team” is an inference this page does not make. For what the finished game actually is — a 1v4 format with Michael Myers as the killer — see the multiplayer overview, which is built from feature pages rather than studio history.

Did the same developers make The Texas Chain Saw Massacre game?

This is the question that keeps following the game around, and it has a narrow honest answer.

• A Texas Chain Saw title is not listed among IllFonic’s own titles. The word does not appear in the studio’s “Titles and collaborations include” sentence, in the game cards on that same page, or anywhere in the text of its home page and Games page as fetched on September 22, 2026. The correct phrasing is not listed — the absence of a title from a company’s own marketing page is not proof about contracts signed years earlier, and this page will not pretend it is.
• The co-publisher does list it. Gun Interactive’s own site keeps The Texas Chain Saw Massacre in its games menu, next to Halloween and Friday the 13th: The Game, describing it as “a third-person asymmetrical horror experience based on the groundbreaking and iconic 1974 horror film.” That page carries a trademark line for Vortex, Inc./Kim Henkel/Tobe Hooper and one for Sumo Digital, but it does not name a developer.
• So the shared name between the two properties sits on the publishing side of the record, not the developer line. Every source used here credits development of Halloween: The Game to IllFonic and stays silent on who developed the Texas Chain Saw game.

If a future official page says something different, that page is the citation and this paragraph changes. Until then, the defensible version of the answer is: the developer of record for this game is the studio that lists Friday the 13th and Killer Klowns, and the Texas Chain Saw title appears in the catalogue of its named co-publisher, not in its own.

Who is named in the official site’s legal line?

The game’s own site answers the licence question in one block of footer text, reproduced exactly:

© 2025 Compass International Pictures, Inc. All Rights Reserved. Halloween and Michael Myers are trademarks of Compass. Game software excluding Compass International Pictures, Inc. elements: ©2025 IllFonic, Inc. All Rights Reserved. Developed by IllFonic, Inc. IllFonic® and the IllFonic Logo are trademarks and/or registered trademarks of IllFonic, Inc. throughout the world. © 2025 Gun Media Holdings, Inc. All Rights Reserved. Gun Media™ and the Gun Media™ logo are trademarks and/or registered trademarks of Gun Media Holdings, Inc. throughout the world.

Read as three registers rather than three co-equal parties: the film property and character marks sit with Compass International Pictures; the game software and the development credit sit with IllFonic; a Gun Media Holdings trademark notice sits alongside both. The site’s logo strip links out to compasspics.com, illfonic.com, and guninteractive.com respectively, so each name is traceable to the entity’s own page.

Note carefully what this is not. A copyright and trademark notice is a rights statement, not a production credit and not a licence agreement. Nothing on these pages says who granted a licence, for what territory, for how long, or who approves creative decisions — the single-player story mode and the Heroes of Haddonfield roster are covered as content, not as rights questions.

How do you reach official support?

One mailbox appears in every place support is published, and it is an IllFonic address:

The official site also carries a social-channel list — X, Facebook, Instagram, TikTok, Bluesky, Reddit, and Discord — which is where announcements appear, though it is not a ticketing route. Billing on a copy bought elsewhere is a storefront matter: the same site links to the Steam, PlayStation, Xbox, and Epic pages, and the editions and price guide covers which tier you bought.

What is not published about the developer and publisher?

None of the sources used here answers the following, and this page deliberately leaves each one open:

• Ownership and corporate structure. No page says who owns IllFonic, Gun Interactive, or Gun Media Holdings, or what relationship “IllFonic Publishing” has to the developer IllFonic beyond sharing a name in the same Steam record.
• Licence terms. The trademark notice names a rights holder; it does not state scope, territory, duration, or approval rights.
• Division of labour. “Co-Publisher” is stored text. No source explains what the co-publisher does versus the publisher, or what marketing, funding, or QA each party handles.
• Staffing continuity. Whether anyone from the Friday the 13th or Killer Klowns rosters worked on this game is unpublished.
• Which office built what. The studio names two US locations and no project-to-office mapping.
• A fourth mark on the logo strip. The official site’s partner logos include one labelled “Further Front”; no page used here states what role it plays, so no role is assigned here.
• Who developed the Texas Chain Saw game. Not stated on any page used here.
• Content plans after September 17, 2026. The most recent official update used here covers fixes and known issues rather than a content calendar, and the Steam record carries one milestone only: coming_soon: false with the date “Sep 8, 2026”. Nothing on these pages dates future content or names a next platform.

How does this affect what you play?

Directly, barely at all — but three practical consequences follow from the record rather than from opinion. The studio that lists Friday the 13th and Killer Klowns is the studio credited with this game’s 1v4 asymmetrical format, so the beginner tips and mistakes page is where that pedigree shows up in play, not on this page. The developer’s mailbox is the only support address either record publishes, so keep the crash-report fields listed above ready before you write in. And the storefront’s required_age of 17 is a property of the content, not of who developed it — that question is settled on the age rating page, which is the one to check before buying for a teenager. For hardware, only the platforms and PC requirements list is verified; studio pedigree tells you nothing about frame rate.
