Biology
The Grineer are genetically modified clones that were created by the Orokin Empire as labourers, they were later modified and militarized using the DNA of an individual who defeated a Sentient assailant. The Grineer are humanoid creatures, descending from the human species. The Grineer are genetically defective due to their genome being damaged by their creators and further more damaged by the invasive cloning procedures they were using. Their defects depend on the individual. Most common defects are rotting skin and reduced intelligence. Their lifespan is shortened to only a fraction of a normal human lifespan. The Grineer compensate for their defects by using cybernetic prosthetics and augmentations.
