Pathogenic Game Organelles

You can reposition freely in the editor

Open the editor with Tab and drag organelles around your pathogen. Connection lines show which infusers touch which weapons; rotating the body changes dodge profile because mass shifts. Community guides call this “free reshape” — Amoeba plasmids lean into it hardest, but every species benefits.

Bind weapons to separate buttons

In the editor, assign slow secretors to right-click and fast spikes to left-click so you are not wasting stamina firing melee at range. Full default binds are on the controls page.

Once slots make sense, the four family table below is the fastest way to judge a new drop.

Flagella — do not skip mobility

Runs that ignore flagella die more to Lungs airflow and heart boss patterns than to low DPS. Dash grants brief invulnerability — use it through projectile walls, not only for travel. At least one speed source before the third organ is a common community rule.

Secretors vs spikes — pick one primary, keep one backup

Secretors win open rooms; spikes save you when macrophages touch your membrane. Most stable builds run one primary family plus one backup weapon on a separate bind. Ranked picks by act are on the organelles tier list.

Mitochondria — the multiplier, not the damage source

Mitochondria rarely kill alone; they spike everything they touch. Place them centrally so connection lines reach both a secretor and its infusers. The next section explains the full five-category layout the game uses under the hood.

Infusers can infuse other infusers

The strongest pathogenic game organelles combos stack infusers so a single projectile inherits burn, fork, and damage amp at once. Order matters — read each card left-to-right along the connection path. Experiment in safe rooms before boss gates; one wrong link is cheaper to fix than a lost heart key.

Actives and support fill gaps

When a room asks for burst instead of sustained fire, actives clean up without reshaping your whole body. Support organs that spawn minions scale with Spore and Virus plasmids especially hard.

Overcharge timing for mitochondria is the next skill ceiling once infusers are linked.

Stacking math in plain terms

Example: a 100-damage secretor with a +25% infuser becomes 125 before mitochondria. If mitochondria adds another +65% to the boosted value, you jump past 200 without any rarity upgrade — the reason players prioritize internal layout over chasing a third weapon.

Pathogen-specific triggers

Nanobot often runs on-hit mitochondria because armor absorbs enough to proc safely. Protozoa prefers movement triggers because it is always dashing. Cross-species notes sit with each entry on the pathogens roster.

Traits on individual organelles can override a perfect mitochondria setup — read those before fusing.

Cancerous spreads on the mesh

When you duplicate an organelle for fusion, Cancerous can jump to adjacent slots. That is how a god-roll secretor accidentally buffs then breaks a mitochondria chain. Isolate Cancerous pieces on an external spike you rarely clone.

Ephemeral recycle (July 22 patch)

If an Ephemeral organelle is about to break and you have more than nine rooms left in the current organ, recycle it for resources instead of letting it vanish. This turned Ephemeral from a trap into a calculated gamble.

Fusion rules below cover when to merge duplicates instead of recycling.

Mutations are separate from organelles

Mutations are permanent run buffs chosen on level-up — extra projectiles, max HP, dash charges — and do not consume graft slots. They stack with organelle synergies; a +1 projectile mutation on a forked secretor is multiplicative, not redundant.

Where to go next

Turn family knowledge into concrete loadouts on the builds page, compare power per act on the organelles tier list, and match species bias on pathogens. New players should still start with the beginner guide if grafting itself is unfamiliar.
