I got it from a local game shop.

The main difference of the board game is that it is coop. So while the single player experience is pretty faithful to the video game and well made, the multiplayer experience is the actual meat of it, and it is a lot of fun. Give it a try if you can.

I would imagine any large boardgame store would carry it or at least be able to order it in.

Last I checked, it was freely available on tabletop simulator
