Recent updates

**2026-09-01** — Brain boss fight guide and damage-scaling mechanics cluster: the [/boss-progression](/boss-progression) page now carries a Brain boss fight guide sourced to the pathogenicgamewiki Brain boss guide — the Brain boss is a boss rush culminating in the named final boss Naegleria Fowleri with a five-attack pattern (dash, ring, lightning, distortion field, fungus traps), five required build roles (sustained single-target damage, repeatable non-kill Overcharge, invulnerability or shield, freeze control, fallback damage), the Fungal Spore minion build (Nidublast + Apex Nidus + Pristine Mitochondrion + invulnerability + freeze + auto-charge), and six failure modes (kill-triggered Overcharge, room-clear-only damage, pure melee, body-enlargement without mobility, no fallback, glass cannons). The [/builds](/builds) page gains a damage-scaling mechanics module sourced to the pathogenicgamewiki Overcharge and Burn build guides: the 7 Aug 2026 additive Overcharge stacking change ('+' tooltips add, 'x' tooltips multiply; +100% + +40% = +140%), Mitochondria chain arrows, kill-trigger vs repeatable Overcharge sources, Burn rarity multipliers (Oxidator doubling at Epic+), Pyroflagellum dodge trail, Pyrogenesis spread on kill, application rate over part count, the Toxisome toxin-vs-Burn distinction (Toxisome does not feed Burn), and the 'Last Room Damage' verification routine. The [/organelles](/organelles) page gains a per-organelle contribution-check module that names the Mitochondrion (Overcharge chain arrows), Oxidator (Burn rarity multiplier), and Toxisome (Toxin vs Burn) on the damage-scaling layer, while keeping the /faq boundary that excludes full per-organelle Codex entries. **2026-08-28** — Seven-pathogen roster and biome-by-biome boss progression cluster: the new [/pathogen-roster](/pathogen-roster) page is a one-stop selection-screen guide that walks each of the seven parasites (Amoeba, Helminth, Bacterium, lil collector, Fungal Spore, Diatom, and the seventh parasite that the allthings.how tier list ranks alongside them) through its unlock condition, body rule, starting values, opening organelle draft, and plasmid-tree investment priority, plus a selection-screen checklist so players can decide their next unlock target. The new [/boss-progression](/boss-progression) page is a per-biome boss progression guide covering all seven bosses (Skin, Intestines, Stomach, Liver, Lungs, Heart, Brain) with each boss's attack pattern, recommended organelle draft and archetype (with reference to the three /builds frameworks — ranged around Secretors, melee around Spikes and Flagella, hybrid split between the two), gating unlocks, and the matching Steam achievement, closing with a Brain true-ending route that also covers the Overachiever unlock path. **2026-08-22** — Post-launch organelle FAQ cluster: the new [/faq](/faq) page answers six post-launch 2026-08-22 questions sourced from the Pathogenic Gameplay Discussions hub for AppID 3808690 and the 7 Aug 2026 Steam News "New Patch: Balancing Adjustments" entry — organelle rarity combine rules (two rares give an epic, two epics give a legendary), Refiner mythic creation (the Refiner can push a legendary organelle up to mythic with enough overcharge), cancerous trait mechanics, attack-infuser vs weapon-infuser, Lil Collector post-patch behavior (DNA pickup range, interact range, and dodge speed all rebalanced), and the melee-vs-ranged contact-damage trade-off. The [/organelles](/organelles) page now carries a "Recent balance changes (7 Aug 2026 patch)" section that names the same Lil Collector pickup / interact / dodge changes plus the Lateral Emitter damage scaling, Katanosome overcharge crit, Phagosome overcharge damage, Peroxisome explosion double-dipping fix, and Mucus Emitter orb growth curve changes from the same patch body.

Pathogenic game at a glance: who made it, where to get it, what to read first

Pathogenic launched on Steam on July 16, 2026, with the public demo having debuted October 31, 2025 during Steam Next Fest. Aberrant Labs is the developer; Slug Disco is the publisher; the Steam AppID is 3808690. Each run casts you as a parasite inside a human host, drafting organelles to assemble and mutate your pathogen, then evolving through branching biomes until the immune system pushes back hard enough to end the run. If your first question is "what is Pathogenic and what kind of game is it," start with the Pathogenic wiki overview. If your first question is "is the 1.0 release out today," the Pathogenic release status page is the dated status answer. If you only have time to read one thing, the Pathogenic wiki overview frames the premise, the Pathogenic demo page tells you how to try before you buy, and the Pathogenic price page walks through every legitimate purchase channel and the promo snapshot.

How to plan your first run

If you already own the game and want a heads-up before your first run, three pages work as a reading order: the Pathogenic beginner guide for room-loop literacy, organelle drafting, and plasmid tree framing; the Pathogenic organelles page for what each organelle does and how organelles physically attach to your pathogen; and the Pathogenic builds page for build archetypes, plasmid tree decisions, and where each pathogen type shines. If you want world context before pressing Start, the Pathogenic biomes page lists the six main progression regions plus the secret Brain level, and the Pathogenic enemies page names the immune cells and rival parasites you will fight. If you collect Steam achievements, the Pathogenic achievements page mirrors the official 41-achievement count from the Steam store.

How this site is organized

The site is laid out so you can drop in at the sub-question you actually have. The Pathogenic wiki overview is the hub anchor. Pathogenic release status, Pathogenic demo, Pathogenic price, Pathogenic system requirements, Pathogenic platforms, and Pathogenic co-op cover the Get Started questions. Pathogenic beginner guide, Pathogenic organelles, and Pathogenic builds live under Play. Pathogenic biomes, Pathogenic enemies, and Pathogenic achievements sit under World. Press coverage lives on the Pathogenic review page. Every page is dated 2026-08-05 and writes dynamic facts such as the active Steam promo, the Steam Deck Verified badge, and the 41-achievement count as a snapshot for that day. Prices and platform lists in particular can change, so cross-check the page's research date before you act.
