Released in 2017, this title is a blend of shooter and hack-and-slash gameplay, available on PlayStation 4, PC (Microsoft Windows), and Xbox One. It marks a significant expansion in the Warframe universe, introducing players to the open Landscapes of Planet Earth. The game centers around the town of Cetus, inhabited by the Ostrons, a community of scavengers. Your primary objective is to defend Cetus and its people from the encroaching Grineer patrols scattered across the Plains of Eidolon.

Core Gameplay

The core gameplay loop involves exploring the expansive environment using parkour maneuvers, stealth tactics, and the Archwing for aerial combat. You'll undertake missions from the Ostrons, primarily focused on engaging and eliminating Grineer forces during the daytime, systematically clearing out their established bases. As you venture deeper into the Plains, the Grineer enemies become progressively stronger, necessitating careful preparation and strategic loadouts.

The Day-Night Cycle

A dynamic day-night cycle introduces a significant shift in gameplay dynamics. As night descends upon the Plains, colossal Spectral Sentients, known as Eidolons, emerge from the waters. These formidable creatures are safeguarded by Sentient drones. While many Grineer soldiers retreat to their camps out of fear, you have the opportunity to band together with other players to hunt the Eidolons. Defeating these massive creatures requires teamwork, coordinated strategies, and specialized gear.

What makes the Plains of Eidolon unique?

The Plains of Eidolon distinguishes itself through its open-world environment, a departure from Warframe's traditional level design. This allows for emergent gameplay and exploration. The introduction of a day-night cycle that dramatically alters the challenges and enemies present adds a layer of strategic depth. The Ostrons provide a hub for missions and interactions, grounding the conflict in a specific location and culture. Hunting Eidolons at night provides a unique endgame activity that requires significant coordination and skill.

Grineer Presence

The Grineer have established drilling stations and outposts throughout the Plains, seeking to excavate Old War technology. During the day, you'll engage in missions to disrupt their operations, but the Grineer will call for reinforcements if they detect danger. The further you venture, the stronger the Grineer forces become.

The Eidolon Threat

At night, the Plains transform as the Eidolons rise from the waters, searching for what they've lost. Small, deadly Sentient drones protect them. While many Grineer retreat, the Tenno can band together to face this threat, requiring great teamwork to succeed.
