Over the weekend, Digital Extremes hosted the latest TennoCon event, celebrating all things Warframe with the game's army of fans. There were plenty of exciting announcements and reveals, including a monstrous look at the game's upcoming co-op expansion, Empyrean.

Empyrean looks set to be Warframe's most ambitious new addition to date, with larger-scale cooperative gameplay, ship-to-ship combat, a new multiplayer Squad Link system, and customisable battleship options amongst much more. You can check out a full 40-or-so minutes of gameplay in the video above, and we've got a description for you below.

Empyrean expands the premise of Warframe by handing players and their clanmates the keys to the powerful Railjack battleship. Prepare to soar through the Origin System, explore new territory, and fight hostile forces with serious firepower! With an in-ship interface to control speed and direction, shield deployment, offensive missile volleys and gunner fire -- including the ability to deploy Archwings and infiltrate enemy ships -- players are now armed with an arsenal of tools to fend off and destroy enemy opposition. Player ships can be upgraded, take damage, and be customized, among many other things.

As well as this, two Warframe updates were shown off, both of which became available immediately. That's right, you can get stuck into these right now:

Nightwave Series 2: Nightwave is Warframe's free, rotating seasonal system. Each Series unfolds over several weeks and tells a brand new story. By completing daily and weekly challenges, Tenno will unlock limited-time, exclusive rewards (gear, cosmetics and more) while experiencing the story as they play. In Series 2: The Emissary players will meet a strange mute child (Arlo) who emerges unharmed from the Infestation and brings with him the miraculous ability to heal the sick.

Wukong Prime Access: Available to earn through gameplay or purchase, the enduring, swift and unruly Wukong Prime brings eager Tenno an enhanced version of the original for the first time ever. Everybody's got something to hide, except Wukong Prime!

And that's not all, either. The team also released a movie-quality cinematic introduction to Warframe from director, Dan Trachtenberg (10 Cloverfield Lane, Black Mirror: Playtest, The Boys, Uncharted). This re-imagination of the game's introductory story presents Trachtenberg's and Digital Extremes' vision of an older era in the Warframe universe and you can watch it in full below.

Phew! Lots of great stuff for Warframe players to get excited about here. Are you a fan of the game? Looking forward to getting stuck into all this new content? Tell us below.
