Saints Row 2 free for PS3 owners who bought Saints Row: The Third
/Kevin Butler's sidekick jack Tretton (President and CEO of SCEA) and THQ promised that the PS3 version of Saints Row: The Third would get an exclusive multiplayer game mode and a special weapon. No such mode or weapon exists in the game.
False promises aside, THQ will be making up for this with something that I think is a much better deal.
THQ's Jon Miller said this,
"For all players that purchase Saints Row: The Third on PlayStation 3 and redeem their online pass codes within the next 90 days, they will receive a digital copy of Saints Row 2 (a $19.99 value)... absolutely free!"
Don't think that this offer is a permanent thing. The promo expires on February 13, 2012 so if I were you, go grab a copy of "GTA on crack" cause you a another game (GTA on not as much crack) for free.
