Infect a host and fight organ by organ from the nose to the brain. Infect Game Mode is the only one that earns XP and adds generations to your virus's lineage, and how far you get here opens the rest of the game.
The big green button on the main menu: infect a host and push through its organs, one boss at a time. It is the only Game Mode that earns XP and makes generations.
Main menu button tagged “Collect: XP”
XP per run: 1 per 3 kills, 8 per room cleared, 150 for a victory
8 organs in order: Nasal Passage, Lungs, Bloodstream, Lymph Node, Gut, Liver, Bone Marrow, Brain
Each finished run becomes one generation of your lineage
A victory means beating the Brain's boss: the host is fully infected
Loaded run modifiers are used up by the run (as in every Game Mode)
From the Codex
Each infected cell releases new virions that go on to infect its neighbours, so an infection can grow exponentially.
Fun fact: A single flu-infected cell can release thousands of new virions within hours.
Before you descend, the game asks you to confirm, because there's no coming back.
Counts how many rooms are still unexplored
Warns that anything left on the floor is lost
Warns when a tumor is still alive: it will metastasize to the next organ at its current stage
Choose Stay or Move on
From the Codex
Viruses spread between organs through airways, blood and lymph: flu can move from the nose down into the lungs, and HIV travels through the blood to lymph nodes.
Fun fact: Inhaled droplets small enough can bypass the nose entirely and land deep in the lungs.
Pausing fills the screen, with the run blurred behind it. On iPhone it has two tabs, Run (everything about the run you're in) and Settings; on iPad and Mac the two sit side by side.
Status strip: organ, kills, extra lives, your host's name and age, and any host condition
Traits: every trait taken, with stacks, plus a Synergies tab
Stats: every stat for this run and where it comes from, with the traits you've picked up
Resources: nucleotides, materials, RNA, modifiers found and gear found this run
Modifiers: what's loaded, each upside and drawback, and any combo
New this run: the briefing card of every first encounter
Challenges: daily, weekly and milestone progress (collect rewards from the main menu)
This room: its tier and every boon and drawback it carries
Settings: sound, vibration, language, controller and keyboard, gameplay data and links, without leaving the run
Every piece of gear the run found, ready to compare, equip or dismantle on the spot.
Sorted by rarity and level
Tap a piece for its stats, abilities, uniques and set
Compared with what you wear in that slot: stronger, weaker or an empty slot
Equip straight from the summary
Pick pieces (or Pick all) and dismantle them for nucleotides
From the Codex
The protein shell that encloses a virus's genome, built from repeating subunits called capsomeres. Most are icosahedral (20 triangular faces) or helical.
Fun fact: Capsids self-assemble: the proteins snap together on their own, like a puzzle that builds itself.
