It's Tuesday which means Steam users have at least one PC game that's been put on sale from now until Thursday. Today that honor goes to Wings of Prey, the recent WWII military flight simulator from developer Gaijin Entertainment. You can download and purchase the game for the next 48 hours for just $24.99, a 50 percent cut from its normal price.

And if you haven't tried the goodness that is Serious Sam HD: The First Encounter, you are in luck. The FPS graphical remake from Croteam is on sale for just $7.49 from now until March 2. The sale extends to the bundle deal where you can purchase four digital copies at once; the price for that bundle is now $22.48 until March 2.

Update: Steam has now put the indie action game Hammerfight on sale for just $4.99 until March 2.
