Pathogenic Controller Support & Steam Input Setup
Configure input and fix common detection problems.
Pathogenic lists controller and shared/split-screen support on Steam. If a device is not detected, enable Steam Input for the game, reconnect controllers before launch, and confirm player-device order before starting local co-op.

Lead with official support, then cover Steam Input, device order, Steam Deck, and safe detection fixes.
Official support at a glance
Start with the exact player question behind “Pathogenic controller support.” This section keeps the answer scannable, defines the terms that matter, and avoids padding the page with unrelated game information.
Facts are separated from strategy. Patch-sensitive mechanics carry a review date, and recommendations are presented as flexible options—not the only correct way to play.
Steam Input setup
Use the system in context. Pathogenic rewards complete chains, so the practical advice here explains inputs, outputs, tradeoffs, and what to do when a run does not give you the ideal component.
Co-op device order and detection fixes
Finish with a decision you can use in the next run. Check the current version, follow the related mechanic or route page, and treat any community strategy as a tested option rather than a permanent rule.
