As they sometimes do, the Steam PC game download site has a new week of PC game sales from a specific publisher, with each sale lasting a day. This week, Steam will put a number of THQ PC game titles on the price chopping block.

For the first daily sale, Steam has cut the prices of the first three games in developer Volition's Red Faction sci-fi shooter series. The first two games in the series are priced at just $2.49 each while the most recent game, 2009's Red Faction Guerrilla, is priced today only at a mere $4.99. All three games are priced at 75 percent off their normal prices until 1 pm Eastern time on Tuesday.
