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.

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?

The Shrine of the Eidolon update rattles with the footsteps of two new towering Eidolons and gives new players the chance to take to the skies with the new flying vehicle, the Dargyn.

Rumors from Cetus have spread sightings of towering, magnificent creatures haunting the Plains of Eidolon at night. In the past, Ostron legends have told in hushed accounts of long dormant Teralysts rising again in special conditions. Debuting together in Devstream 103, the Gantulyst is a soaring new beast, nearly twice the size of the original Teralyst (first introduced with Plains of Eidolon), wielding a rock for an arm and capable of hurling a massive ball of energy that rotates and radiates powerful beams of Sentient energy in all directions. The Hydrolyst is a toxic, deadly creature more powerful than its giant brethren. It creates toxic storm clouds, pouring out poisonous Sentient energy that deals constant damage, challenging the most experienced Tenno like never before.

Players will learn from previous battles against the original Teralyst confrontations how to apply those team lessons to coordinate new strategies to defeat the new mammoths at hand. But they must also discover when and how the new Eidolons appear on the Plains. Once defeated, rewards for defeating each will be plentiful. What could the new Eidolons be after, and how will Tenno uncover the purpose of their troublesome nocturnal flights?

While in search of solving these bigger mysteries, players now have a faster way to transport across the Plains. With the introduction of the Dargyn, a solo airborne craft used by Grineer to patrol, players can now power-glide across geography more quickly than on foot, or light up unsuspecting Grineer combatants by making use of the vehicle's quiet engines and built-in weaponry. Squads of players – of any experience level -- can coordinate teams of two, three of four to dominate Earth's skies day or night to take on enemies small and large. The introduction of the Dargyn to players complements the existing Archwing as a secondary aerial method of moving through the Plains, handling players more options and tools to succeed. What mayhem can Tenno cause to the growing Grineer presence?

Already available on PC, the free Shrine of the Eidolon update comes to PS4 and Xbox One next week
