Steam has kicked off its Exploration Sale, discounting a number of popular franchises, several adventure games, and a whole lot more.

In addition the Fallout and Tom Clancy series, the Cid Meier's Civilization and Company of Heroes franchises have all received considerable markdowns as high, as 75 percent off. It's worth noting, however, that Fallout 4 is not among the Bethesda-developed post-apocalyptic RPGs featured in the sale.

Other key discounts include Ori and the Blind Forest, ARK: Survival Evolved, and Darkest Dungeon, all of which are currently 40 percent off. Additionally, a handful of adventure titles including Life is Strange and The Walking Dead are 50 and 75 percent off, respectively.

Over eight thousand titles are currently on sale, all of which you can check out at Steam's online store.

The Exploration Sale is live now and will run until December 1 at 10am PT.
