In *POLYMORPH*, the thing that heals you is a caterpillar—a soft, unbothered creature trundling through the level on its own business—and to use it, you have to kill it. "Health packs are creatures in *POLYMORPH*," reads [the June reel](https://www.instagram.com/p/DZdAjtBRLdB/?ref=killscreen.com) from the game's account, and the comments did exactly what the design wants: fell for the caterpillar, bargained for its life, and started theorizing optimal predation—including whether the worm should stop moving once its head is gone, so you could plan when to harvest it.

The **POLYMORPH* announcement reel, via [the game’s account](https://www.instagram.com/p/DZdAjtBRLdB/?ref=killscreen.com). Sound on.

The game, [due on Steam in 2026](https://store.steampowered.com/app/4192080/POLYMORPH/?ref=killscreen.com) from Intron Interactive, inverts the body-horror shooter's usual scale: you play the disease. A "cancerous pathogen," per the store page, mutating through procedurally generated host vessels while antibody swarms hunt you—120-plus mutations, five hostbodies with names like Flamingo, Wheeler, and Jelly, randomly generated flesh dungeons, a gamble-heavy merchant. The crew credited on the announcement includes Vince McKelvie, a veteran of the gooey, hyper-saturated 3D net art this game's look descends from directly.

Making the healing item a bystander is a small design decision with a long moral shadow. Most games launder resource extraction into abstraction—a crate, a cross, a glowing orb. *POLYMORPH* restores the transaction's victim and gives it a face, which is thematically airtight for a game about being cancer: you don't defeat the body, you consume it, one sympathetic organism at a time.

Killscreen has a long-standing soft spot for games that make flesh the level geometry—we were watching [*Scorn*](https://www.killscreen.com/scorn-slowly-reveals-fleshy-face/) slowly reveal its fleshy face nearly a decade ago. *POLYMORPH* plays the same material for comedy and guilt instead of dread, which might be the more unsettling register. Wishlists are open now.
