Wasteland 2 is available on Steam Early Access for $60, a fee that grants players Wasteland 2, the original Wasteland, the Mark Morgan soundtrack, and Wasteland digital novellas and art book. InXile's Wasteland 2 was funded via Kickstarter in 2012, raising $2.9 million from 61,000 backers. Those who contributed $55 or more got access to the beta yesterday.
InXile shows off some Wasteland 2 gameplay in the gritty "Butchers of Arizona" trailer. Relatedly, it's a temperate 70-ish degrees in Phoenix right now. You gotta take the good with the bad.
