As plenty of you know, the limited edition of Gears of War 2 comes with a Golden Lancer for use in Multiplayer. There was also a limited freebie of code packs for a Golden Hammerburst given away at the Midnight releases in various stores. I went into my Gamestation today in Torquay to see if they had any free and they had a fair few and gave myself and my friend one just for asking.
So not a guaranteed freebie, but try asking for this at your local Gamestation (don't know about Game) and you might be running around in Multiplayer with a very limited Gold Hammerburst! Good luck! :D
