Crude Oil Unit Types Guide

Introduction to Crude Oil Unit Types

In Crude Oil, your primary form is a sentient puddle of crude. As you consume more oil and evade the relentless pursuit of the MegaPetro corporation, you can evolve into different unit types. Each unit type offers unique advantages in speed, size, and combat capabilities. Understanding these forms is crucial for progressing through the game's challenges and eventually washing the polluters down the drain.

This guide breaks down every known crude oil unit type, including their stats, unlock conditions, and strategic uses. Whether you are a new puddle or a seasoned slick, mastering these forms will help you survive the industrial onslaught.
