The Steam Summer Sale isn't the only way to save money on PC games at the moment. Right now you can grab a full copy of Shadowrun Returns Deluxe for free from the Humble Store. The game normally sells for $25, making this a killer deal for anyone who's interested in tactical RPGs. All you need is a Steam account and a Windows, Mac, or Linux machine capable of running it. But hurry--the deal ends Saturday, June 23.

Shadowrun Returns Deluxe is a cyberpunk-meets-fantasy game that's set in 2054, after magic has returned to the world, along with elves, trolls, orks, and dwarves. You play as a shadowrunner on the hunt for a killer in a dark, futuristic version of Seattle that's been overrun by mega-corporations.
