About IllFonic
IllFonic makes and publishes action and adventure games, many of them third-person shooters where one side hunts and the other survives. The studio has built much of its reputation on well-known screen licences, from the jungle stalking of Predator: Hunting Grounds to Ghostbusters: Spirits Unleashed, Halloween: The Game and Killer Klowns from Outer Space: The Game.
Alongside those licensed projects sits Nexuiz, a faster, arena-style shooter that shows the studio's roots in competitive first-person action. Taken together, the releases span 2020 to 2026 and sit firmly in the action games and adventure space.
Games in the IllFonic catalogue
Predator: Hunting Grounds and Nexuiz are listed as Steam keys, while Halloween: The Game and Killer Klowns from Outer Space: The Game come as keys, accounts or gifts, with Killer Klowns also covered on Xbox Series X|S. Ghostbusters: Spirits Unleashed is listed for Steam and Xbox One.
Deluxe editions and add-on content make up a large part of the range, including Halloween: The Game Deluxe Edition, the Killer Klowns from Outer Space Deluxe Edition, Predator Bundle content for Predator: Hunting Grounds and bonus content for Killer Klowns on PlayStation 5. Add-ons need the matching base game on the same account before they can be used. PC buyers will find most of the range among Steam keys.
How buying works
Each listing activates on the platform it names: Steam titles are redeemed in the Steam client, Xbox One and Xbox Series X|S titles on an Xbox account, and PlayStation 5 content through the PlayStation Store. A key is a code you redeem on your own account, so the game stays with you afterwards. An account comes with the game already on it and is signed into rather than redeemed, which suits titles where a key is not available for your platform.
Games are sold per region, and a key has to match the region of the account it is used on, so check that pairing before redeeming. Step-by-step help is in the Steam key activation guide and the notes on region locking.
Common questions
- Which platform does an IllFonic game activate on?
- The platform named in the listing. Steam titles redeem in the Steam client, Xbox versions on an Xbox account and PlayStation 5 content in the PlayStation Store.
- Will a key work in another country?
- Only if the key's region matches the region of the account you redeem it on. A key sold for one region will usually be refused by an account registered elsewhere.
- What is the difference between a key and an account?
- A key is a code you redeem on your own account. An account arrives with the game already on it, so you sign in with the supplied details instead of redeeming anything.
- Do deluxe editions and DLC need the base game?
- Yes. Add-on content such as the Predator Bundle or the Killer Klowns bonus content requires the matching base game on the same account and platform.
- When do I get my key or account details?
- The key or account details are delivered to your order once payment completes.
