Steam's regular Tuesday mid-week sale is now in effect and this week the game that gets the honors is Trine. The innovated puzzle-action game from developer Frozenbyte is now on sale for just $5 from now until Tuesday. That's a big 75 percent price cut from its normal price.

Keep in mind that Steam also has another sale going on from now until Monday. As we reported yesterday a number of Sega's Total War RTS games are now on sale for 66 percent off their normal price. Also the downloadable content for Empire: Total War is on sale for 10 percent off until Monday.
