Pathogenic puts you in the shoes of a disease, and that disgusting idea makes one of the most original roguelikes of the year

We've played heroes, monsters, gods and octopuses. We'd never played a disease. Pathogenic fixes that gap with an idea as repugnant as it is brilliant: you're a pathogen, a lone cell released into a human body, and your mission is to infect it by devouring everything that resists you. It's grim, it's fascinating, and it's above all one of the freshest roguelike concepts we've seen in a long time.

The context

Pathogenic is a cellular roguelike shooter developed by Aberrant Labs and published by Slug Disco, available since 16 July 2026 on PC, Mac and Linux. The pitch is as simple as it is disturbing: you're a disease, a lone pathogen that must conquer a beautifully rendered, procedurally generated human body, in a microscopic arms race against its host's immune system. Slug Disco, already known for its fascinating colony simulations, confirms here its taste for the miniature living and turns cellular biology into a playground of rare originality.

The gameplay: loot, graft, mutate

The heart of Pathogenic is its evolution-by-looting system, and it's brilliantly conceived. You don't grow in power by earning abstract levels: you hunt enemy cells, you literally rip out their organelles, and you graft them onto your own body to evolve. You go from a simple cell to a complex engine of destruction by assembling dozens of organelles with precise functions: flagella for movement, mitochondria for power, secretors for ranged attacks, spikes for melee. Each run becomes a unique organic construction, shaped by what you managed to steal from your prey.

With more than a hundred organelles and mutations in the full game, the build depth is real, and that's where the game hooks. You experiment, you combine, you look for synergies, you cobble together a cellular monster in your image, exactly in the spirit of the best roguelikes. Facing you stands a whole believable immune bestiary, from macrophages to T cells, not to mention rival parasites like tapeworms or protozoa fighting over the same host. That biological arms race, where the host defends itself better and better as you grow, gives the game a tension and a thematic logic perfectly held.

Soft-body physics, the real signature

What gives Pathogenic its unique flavor, beyond its concept, is its soft-body physics. Each cell, each projectile is simulated to interact in a physical, organic way, and it changes everything in the feel. The clashes have a viscous, gelatinous texture, where everything trembles, deforms and stretches, and that materiality makes each impact strangely satisfying. You don't fire bullets at sprites, you fling living matter against living matter, and the result is as repugnant as it is joyful. It's the kind of technical detail that turns a good idea into a strong identity.

That organic approach irrigates the whole art direction. The human body, rendered as an environment both beautiful and unsettling, becomes a real game setting, colorful, moving, alive. Slug Disco understood that the microscopic scale was an untapped visual goldmine, and the studio draws captivatingly strange tableaux from it. You explore the innards of a human being as you would explore an alien planet, and that sense of displacement is a success in itself. Pathogenic is as pleasant to look at as it is clever to play.

What we take away

Pathogenic is exactly the kind of game you want to defend: a roguelike unafraid to start from a weird idea and push it all the way. Playing a disease that evolves by looting its enemies' organelles is a concept of total freshness, served by a deep build system, a believable immune bestiary and soft-body physics that give it an immediate signature. Slug Disco confirms its talent for making the miniature living fascinating, and delivers a roguelike shooter that clearly stands out in an otherwise crowded genre. You come back to test a new organelle combination, again and again.

Like any roguelike, it will have to prove its depth over time, and its success will rest on the real richness of its synergies across dozens of runs. But the base is excellent, the idea is memorable, and the technical execution, notably that organic physics, places the game above the fray. For anyone seeking a roguelike that truly steps off the beaten path, in both substance and form, Pathogenic is a little disgusting gem we recommend without hesitation. Sometimes, all it takes is daring to be a disease.

Verdict

A cellular roguelike shooter with a concept as repugnant as it is original, where you evolve by looting your enemies: a fresh idea, a deep build and soft-body physics that make it one of the most singular of the year.

Strengths:

• A concept of total freshness, playing a disease that loots to evolve
• A deep build system, more than 100 organelles and mutations
• Soft-body physics that make each clash joyful
• An art direction that makes the human body a fascinating setting

Weaknesses:

• The depth of synergies across dozens of runs remains to be confirmed
• An organic, gooey concept that won't win over the squeamish
• The difficulty proper to the genre, which demands perseverance
