Warframe: Plains of Eidolon - Guides

The Grineer have organized drilling stations and sprawling outposts throughout the Plains to excavate the technology of the Old War. Take missions from the Ostrons to fight Grineer during the day and clear out their bases, but be fast, as these Grineer will call reinforcements when they spot danger. As you venture deeper into the Plains the Grineer enemies will get progressively stronger, so come prepared.

When night falls on the Plains, towering Spectral Sentients known as Eidolons ascend from the waters and wander in search of all they’ve lost. Small, deadly Sentient drones appear throughout the Plains to protect the Eidolons. Many Grineer will retreat to their camps in fear of the Eidolons and attempt to wait out the night.
Gather your fellow Tenno. You'll need to work together to take down these massive creatures. Only the greatest Eidolon Hunters that combine forces will reign victorious.
