Valve has once again brought upon the PC crowd the ultimate savings catalogue for their digital distribution service with the launch of Steam's Autumn Sale 2013, putting a number of titles up for deep discounts to make your wallet cry out in pain.

As usual, Valve is continuing its sales trend with nine games available in the Daily Deals section, some of which you probably should already own but if not get them while they are cheap!

Outlast

Left 4 Dead 2

Sleeping Dogs

Terraria

The Elder Scrolls V: Skyrim

Prison Architect

Rogue Legacy

AntiChamber

The Walking Dead

Flash sales have also returned to Steam, with four new titles popping up every eight hours to tempt your growing backlog of games. Currently up for grabs is Space Hulk, Crysis 2 Maximum Edition, Castle Story and Hammer Watch.

As always when it comes to a Steam Sale it's always best to wait until the game you want is actually on the Flash or Daily sale, in order to get the most savings possible.
