Warframe Game Guides
Warframe Factions: Grineer, Corpus, Infested, and Sentient
Every Warframe mission features one or more enemy factions. Understanding how they fight helps you pick mods, elements, and positioning — whether you are new or returning after a break.
Grineer — armor, density, and heavy units
Grineer missions feature armored units and heavy enemies that punish slow clears. Corrosive and armor-strip setups are common. Read faction detail on the Grineer Wiki page.
Steel Path Grineer defenses are a classic choke-point test — see our Steel Path guide.
Corpus — shields, proxies, and robotics
Corpus enemies rely on shields and robotic proxies. Magnetic, toxin, and shield-break tools matter more here. The Corpus Wiki page lists unit types you will see in void and ice tilesets.
Digital Extremes occasionally rebalances proxy spawns — watch official PC update notes when a Corpus-heavy update ships.
Infested and Sentient — special mechanics
Infested missions emphasize swarm pressure and constant spawns. Sentients appear in later content and adapt to damage types — the Sentient Wiki page is essential before Eidolon or Circuit-style content.
Knowing faction spawns also helps you filter ESP categories — covered on our wallhack page.
Use official references first
For lore and faction history, Warframe and Warframe Wiki beat random summaries. For balance changes, trust official PC update notes and developer streams from Digital Extremes.
