Wasteland 2: Director's Cut is out today on desktops, consoles in North America
Wasteland 2: Director's Cut has been released for Linux, Mac and PC.
You can grab the game through Steam and GOG and it comes with a copy of the original Wasteland and all other content released.
Other online digital PC stores such as Origin will have the game available over the course of the next day or so.
Those who already own Wasteland 2 on Steam or GOG just need to hit up their Steam library or GOG account page and find the Wasteland 2: Director's Cut game entry. It can then be downloaded separately and won't replace the original game.
PS4 and Xbox One retail and digital releases are scheduled for today in the Americas, and October 16 for Europe.
