Evolution Preview

Use Pathogenic evolution preview to test organelle layouts before confirming, cancel pickups, and avoid empty slot warnings at run start.

What Evolution Preview Does

Evolution preview is a quality-of-life feature added in pre-launch patches and retained for Pathogenic 1.0. When you reach an evolution choice, you can swap between layout options and preview how organelles fit before pressing Evolve to confirm. This replaces blind commits that used to lock incompatible grafts until the next shop or mutation altar.

The preview phase lets you experiment with adjacency for organelle traits introduced at launch. Drag virtual layouts, inspect trait lines that flip green or red, then switch evolution types to compare outcomes. Only the confirmed evolution applies—exiting preview without evolving costs nothing.

You can also cancel an organelle pickup before it attaches if you mis-click loot on the ground. Combined with warnings when starting a run with empty weapon slots, the system reduces early Skin deaths from accidental empty builds.

Preview Workflow in Practice

Open preview whenever an evolution offers multiple body shapes—especially Amoeba slot expansions and Helminth reach layouts. Compare Mitochondria cluster density before confirming. Two seconds in preview often saves a ruined Intestine route when a trait requires three adjacent Spikes.

Use preview after major loot spikes, not only at formal evolution gates. The Tab editor still handles mid-run rearrangement, but evolution preview is the only time you can test entire layout archetypes without spending currency.

Pair preview with our organelle traits and how-to-play guides when learning graft rules. Remote Play Diatom partners should agree on preview pauses so neither half drags the body during layout tests.

Common Mistakes to Avoid

Confirming evolution while trait lines show red wastes the only free full-layout test for that gate. Scroll every evolution option even if the first looks fine—Amoeba sometimes hides optimal slot counts on the third layout.

Ignoring empty-slot warnings at run start leads to weaponless Photosynthesis accidents or challenge mode failures. Fill at least one damage source before leaving the loadout screen.

Preview does not simulate shop stock or daily modifiers. A layout that previews well may still fail under Phagocytosis melee-only rules—read challenge cards separately.

Frequently Asked Questions

Can I preview without evolving?

Yes. Swap layouts freely until you press Evolve. Canceling leaves your previous body intact.

Does preview work in co-op Diatom?

Both players should pause communication during preview. Only the host evolution choice applies to the shared body.

Is preview available on every pathogen?

All pathogens with evolution choices use preview at 1.0. Amoeba benefits most due to slot growth.
