Steam is getting in the sale spirit with its own deals week that has just kicked off and will run through December 3. There will be different games on sale each day, and already today we've got 75% off Left 4 Dead 2 and The Walking Dead for Mac.

Steam generally knows how to do deals well, and with the catalog of games at its disposal it's well worth keeping your eyes on this one every day. The added benefit to Steam is of course that should you be using a Mac, Windows or Linux machine Steamplay means you've got all your games on all your compatible machines. Take a look and let me know if you see anything that takes your fancy!
