Grineer Empire

A violent matriarchal race of militarized human clones locked in an endless war.

The Grineer are a violent, war-driven matriarchal race of militarized human clones. Originally created by the ancient Orokin Empire, they now serve as one of the primary factions in the Origin System, locked in an interplanetary war against the Tenno and other groups. Their society is defined by endless conflict and a rigid hierarchy where survival depends on service to their rulers. Unlike the profit-driven Corpus or the disfigured Infested, the Grineer are purely focused on warfare, acting as a relentless force that seeks to dominate any system they encounter.

Lore & Background

All factions in the Origin System, including the Grineer, trace their origins back to the fallen Orokin Empire. Before the empire's collapse, the Orokin faced resource depletion and sought to colonize new star systems by sending ships through the Void. They also dispatched Sentients to terraform the Tau system for future colonies. However, the residential ships never returned; those carrying Sentients came back intending to wipe out their creators.

This conflict, known as the Old War, led to the creation of the Tenno and the eventual fall of the Orokin. The Grineer Queens are shown to have their origins as far back as the old Orokin Empire. By the time the Tenno awaken from centuries of suspended animation on Earth, the Orokin are virtually dead, yet their influence lingers. The Grineer now operate as a violent matriarchy, ruled by Queens who command their clone legions in a constant state of war.

Reader's Guide

Players control members of the Tenno to complete missions against various factions, including the violent matriarchal race of militarized human clones known as the Grineer. The game features both player versus environment and player versus player elements. Missions often take place on procedurally generated maps where players must defeat specific numbers of enemies (Exterminate), steal data without raising alarms (Spy), rescue prisoners, or defend points for set periods.

Later updates added three large open-field environments and a fourth named Duviri. High-difficulty daily and weekly challenges offer rare rewards. The Grineer are encountered throughout the Origin System as part of the interplanetary war. Players use weapons, abilities, and parkour maneuvers to navigate missions.

Support for cross-platform play was released in 2022, with cross-platform save rolling out from December 2023 to January 2024.
