A bacterial immune system that remembers viruses and cuts their DNA with the Cas9 enzyme; scientists adapted it into a precise gene-editing tool.

The ultimate power-up, rarer than any element: it can drop from the first few cells you kill in a fight. For 10 seconds you're invincible and faster, and every cell you touch is cut apart.
Fun fact: Its discoverers, Jennifer Doudna and Emmanuelle Charpentier, won the 2020 Nobel Prize in Chemistry.
Fever is the body setting itself on fire on purpose: a hotter body slows viral replication.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: four flamethrower jets spin around you, setting cells burning.
Mucus and fluids constantly wash the airways, sweeping trapped viruses up and out.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: waves pulse out of you, pushing cells back and washing away shots.
A sneeze can launch droplets at over 30 m/s, carrying viruses metres away.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: you move much faster and blow enemy shots back at them.
Some infections leave calcified scars behind, hard lumps of minerals the body builds around damaged tissue.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: take far less damage; boulders orbit you, crushing cells and blocking shots.
Cold slows chemistry down: frozen viruses can stay infectious for years, which is how labs store them.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: every cell near you is slowed, and may freeze solid for a moment (not bosses).
Aerosols, the fine mist of a breath or cough, can hang in the air for hours carrying viruses.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: most hits miss you, and cells in the mist are poisoned.
Out of sunlight, viruses on surfaces survive much longer; darkness protects them from UV.
In the game
An elemental power-up that can drop from the first few cells you kill in a fight. For 8 seconds: a wide dark aura drains cells fast to heal you, drained cells burst into shadow novas, and your shots hit much harder.
