That's right, Dead Rising 4 did come out on December 6 last year, after all those big game releases.
It was released on Xbox One, but the most recent titles now come on the Windows 10 PC as well. Now after three months, the zombie open world game is available in a more known platform - Steam. You can check the game's Steam page here.
It's hard to keep track with all these games out now, especially with the first quarter being a crazy good start for 2017. The more options the better I guess.
