Set in the far reaches of outer space during a new Dark Age, WarFrame introduces the Tenno, a race on the brink of extinction after being enslaved by the Grineer for centuries. Players enter WarFrame on the cusp of the Grineer's victory over the Tenno until they begin to arm themselves with WarFrames - an ancient exo-skeletal technology only they can operate. Hidden within the Orokin Derelicts of a lost civilization, new WarFrames lie dormant and undiscovered. These artifacts are the Tenno's only hope for survival.

WarFrame is a free-to-play fast-action PvE shooter set in an evolving sci-fi world. Some would call it MMO-Lite as squads of four players band together to advance their characters and battle the oppression of the genocidal Grineer. Throughout their combat missions, players will continually increase the power and abilities of their WarFrame and weapons. Players will raid new areas of space searching for exotic and powerful weapons and WarFrame augmentations to customize their arsenal. With WarFrame's Automatic Mission Generator, the game will offer endless replay as levels are procedurally configured for a unique raid -- every time.

With Plains of Eidolon's, Digital Extremes' new Open Zone design offers a vast new geography packed with exploratory daytime activities and towering night-time battles unlike anything Warframe players have seen before.

In Plains of Eidolon, players will discover a brand new experience vastly different from the maze-like tilesets they've known. For the first time in Warframe, players will see exquisitely lit vistas with an ongoing day/night cycle that creates an alluring continual emotional experience of dawn, day, dusk, and night. In the day-time, Tenno (players' in-game name) will have the freedom to seek missions from colorful vendors in the makeshift colony of Cetus, including as many as 50 other players with which to socialize. Players will cajole and converse with an eclectic collection of vendors like mining experts, fish mongers, beast masters, mask makers, and weapon smiths, the latter of which enables players to create a series of modular weapons, customized to their tastes like never before.

Outside of town, solo or in squads of up to four, players can freely explore the Plains. Filled with stunning lush hillsides, busy lakes and rivers inhabited by schools of underwater creatures, and hidden cave systems, Tenno can entertain themselves with mini-games such as spearfishing and mining to gather resources, or engage in heroic land and air battles -- using the reworked Sky Archwing -- against an ever-belligerent Grineer presence.

Best of all, daytime activities are available to all players of any experience level! But once night falls, enemies scatter and hide as the plains are haunted by mammoth Sentients. Summoned by a mysterious force, the towering Spectral Sentients known as Eidolon ascend from the waters and threaten all living things in their paths. What do they search for every night? What will it take for your team to defeat them?

Warframe's Plains of Eidolon expansion has broken performance records and reached all-time highs following its Thursday, October 12 launch on PC.

With the Plains of Eidolon expansion, Warframe hit an all-time peak of 121,377 concurrent players on Steam, nearly double its previous record of 69,526 CCU peak in March 2017 with Octavia's Anthem, making it the second highest peak CCU for a free-to-play game currently on Steam. Warframe Plains of Eidolon rocketed to the top five of SteamCharts, racking up 40,145,054 hours played (as of this writing) by enthusiastic Tenno.

Key features in Plains of Eidolon include:

• Debut of the Deadly Warrior: Witness the introduction of the 34th Warframe, Gara, who manipulates glass to fracture the resolve of her enemies. Gara's unique Abilities comprise Shattered Lash, which thrusts forward a deadly glass blade, or performs a 180-degree sweep, damaging anyone in its path; Splinter Storm, which surrounds her target with swirling shards of glass; Spectrorage, which creates a ring of mirrors around a target area, and Mass Vitrify: an Ability that expands a ring of molten glass slowly crystallizing enemies who enter.
• New Weapons: Gara wields a new arsenal of powerful weapons, including:
  • Astilla: The deadly Astilla shoots slugs that explode on impact, dispersing lethal glass shards in all directions
  • Volnus: The heavy Volnus deals a large amount of damage and can beat enemies to a pulp, providing you have the strength to wield it
  • Fusilai: The stealthy glass shurikens pierce through flesh and armor, taking down enemies unheard
• New Reinforcements:
  • Argonak: Pick off targets by highlighting distant enemies using this Grineer rifle's advanced laser sighting system. Deadly in both single fire and automatic modes
