From ShockblastMedia.com "One of the best deals I have ever found on a video game came with the purchase of the game Darksiders. I bought the game used at Gamestop and when I brought it home and got ready to fire it up, I noticed that there was a slip inside that let me put in for a free copy of the game Red Faction: Guerrilla. $5 for shipping later, I got two killer games for about 25 bucks. Had it not been for that slip, a game like Red Faction more than likely wouldn't have been on my radar. Having played it a bit and enjoyed pretty much bashing the hell out of the entire planet of Mars, the subsequent addition to the franchise was very quickly high on my priority list."
