Guide

01 Getting started in the lab Picking a preset and releasing it into the lab is everything you need to do to get the game moving.
02 What parasites actually do No two parasites grow the same way, so experimenting with different presets is the core loop.
03 Contracts and progression Contracts give you structured goals, added in Update 8.
