How do you get the free codes gears of war games?

I played ultimate edition Now what? I haven't received anything, Do i have to wait?

MS sent me a message with the codes.

I never got my codes either.

I own digital copies of GeoW1, GeoW3, and GeoW:J.

So GeoW Ultimate only had to give me GeoW2 for my set to be complete, but I got nothing so far.
I believe they are also going to send codes Dec 1st though.

@legaldruggie: I made sure I played offline and online. That might be the key. I already got mine. Loving Gears 3 campaign again. Those games are just great 3rd person shooter fun.

message as in an email you signed up on xbox live with?

Nah, just a message through Xbox Live.
