For the next three days, Valve is highlighting a specific genre of game for its next sale. The Steam Stealth Game Sale starts on October 13 and ends on October 16 at 10 am PDT.
A total of 64 games are up for grabs, with the list varying from well-known franchises such as the Splinter Cell series and Deus Ex games, to smaller titles such as Invisible Inc. and Volume. However, there are a few titles that seem out of place, most notably Metal Gear Rising: Revengeance, which is typically known as a hack-and-slash title, yet contains some form of stealth at a few points in the game.
Prices range from as low $0.99 for the 2008 game Death to Spies to $33.49 for Far Cry 4, the latest game in a series (not counting the recently announced Far Cry Primal, of course), so if you have a few dollars to spare, grab some stealth games.
Update, 10/13/2015, 1:14 pm PDT: We incorrectly put the number of games on sale. The correct number has been added.
