Warframe's upcoming Plains of Eidolon expansion will introduce the very first open-world zone, the aforementioned Plains of Eidolon. You can expect to see the usual batch of enemies such as the Grineer, but also a whole bunch new and absolutely enormous alien creatures known as the Eidolons. In order to take them down you will need to group up with your fellow players as they will present quite a challenge, but if organized play is not your thing there will also be bounties to collect, new items to craft, and quests to solve.

Besides all of the open-world content, the Plains of Eidolon expansion will also bring with it new weapons, cosmetics, crafting recipes, improvements to the Focus talent tree, as well as a brand new glass-based Warframe by the name of Gara, though she will be coming slightly after release. If you're wondering what all of this content might look like in-game, wonder no more as the developers have recently posted a lengthy gameplay preview. Have a look:

There are far too many details for me to cover in brief, so if you're interested in learning everything about the Plains of Eidolon you'll find what you seek on the official website. The developers have done an excellent job of highlighting just about all of the major changes and additions, so you should get a pretty good idea of the sort of gameplay Plains of Eidolon will be bringing with it.

The Plains of Eidolon expansion will be coming to PC and Steam next week, though I'm afraid the release date hasn't been revealed just yet. As for the consoles, the update will be slightly delayed, though thankfully not for too long as it will be coming this November. And finally, here's a couple of the new images, just to set the mood:
