If you took advantage of the offer for a free copy of Red Faction: Guerrilla via the "mystery code" inside new copies of Darksiders -- and if, for some reason, you've been avoiding your mailbox -- now is the time to face the rush of junk mail once again. You might have a free game waiting for you!

We've begun hearing from tipsters whose freebie Red Factions have arrived. The timing couldn't be better for THQ: having just announced the PC release of Darksiders yesterday, the arrival of the promo discs gives us cause to bring up the game again in posts like this one! We see what you did there, THQ.

[Thanks Ben!]
