An action roguelike: become a leucocyte hunting viruses, bacteria, and fungi in a petri dish, choosing a mutation path and stacking weapons to survive ever-deeper Rifts.

<h2 class="bb_tag" >Petrix</h2>You are a leucocyte. The battlefield is a petri dish. The enemy is everything else.Dive through procedurally-escalating Rifts, fighting off swarms of viruses, bacteria, and fungi as you build toward devastating late-game power. Every kill earns Aether and Mutagen — spend them between dives at your Safe Zone to permanently reshape how you fight.Choose your mutation. Commit to one of four elemental paths — Fire, Frost, Lightning, or Shadow — each with its own skill tree and a run-defining Tier 4 ultimate: scorch the arena with Solar Flare, freeze it solid with Absolute Zero, chain lightning through Tesla Storm, or vanish and strike with Shadow Shroud.Face down real bosses. Four boss archetypes — Virus, Bacteria, Fungus, and Splitter — each fight differently and demand different answers. Push deep enough and you'll face two at once in a full-blown Outbreak.Arm yourself. Stack up to seven auxiliary weapons alongside your beam — chain lightning, deploy turrets and mines, launch homing missiles, summon orbiting satellites, and more — and find the combinations that turn a desperate dive into a one-cell army.Learn what you're fighting. Every boss and mutant strain you defeat unlocks an entry in the Compendium — real microbiology, decoded one kill at a time.<h2 class="bb_tag" >Key Features:</h2><ul class="bb_ul"><li>Four mutation paths with deep, exclusive skill trees and unique Tier 4 ultimates</li><li>Four core boss archetypes plus elemental variants, with dual-boss Outbreak fights in deeper Rifts</li><li>Seven auxiliary weapons to mix and match alongside your primary beam</li><li>A 50-entry Compendium of real microbiology, unlocked through play</li><li>Full gamepad and keyboard/mouse support</li><li>Steam achievements</li></ul>
