Nier: Automata comes with a Valve accessory you can attach to 2B’s head when you pre-purchase on Steam
The Day One Edition of Nier: Automata is up for pre-purchase on Steam, and it comes with a rather familiar item which you can attach to 2B's noggin.
The Day One Edition for Nier: Automata on Steam is almost identical to the PlayStation 4 version, save for the console exclusive Play System Pod Skin and of course, the red valve accessory on Steam.
2B can wear this item in various ways, as you can see below.
If you aren't familiar with the accessory, here's a couple of images for reference:
The Valve character accessory will only be available for a limited time, so if you want it, it'd be best to go ahead and pre-purchase the game through Steam.
If you missed the PC release date announcement, you should head through the link and give the PC specs the once over.
Nier: Automata is out now in Japan and will be released on PlayStation 4 with PS4 Pro support March 7 in North American and March 10 in Europe. It hits Steam March 17.
