NieR: Automata has already arrived to the PlayStation 4 in the US, but for the rest of us in Europe or on the PC there is still a little bit of a wait. Europe will be getting the PlayStation 4 version on March 10th, while the PC version will have a simultaneous global release on March 17th.
In order to give everyone an idea of what Nier: Automata is even all about Square Enix has recently posted a brand new trailer going over the story, gameplay, and environments we'll get to mess around with. And don't worry about spoilers because the story content is incredibly vague and mostly meant as an appetizer. Anyway, have a look:
On the other hand, if you're looking for a detailed overview of the combat and the open-world exploration you'll find a developer-guided preview over here. The video is about 30 minutes in total, but it features pretty much everything you can do in NieR: Automata, so if you have a bit of free time make sure to give it a look.
And finally, it is also worth mentioning that the PC system requirements have recently been revealed. Long story short, you'll be glad to hear that NieR: Automata's requirements are quite a bit lower than what you've come to expect from modern AAA games, so even if you have an under-powered CPU you might just be able to run it at a decent framerate.
