Okay I did this on a different forum, and my message got moderated (apparently I was spamming...) so I don't know which ones have been used, hopefully some still work.
Now these are the download cards that came with the collector's edition for Halo Wars, so you get some multiplayer maps for Halo 3 (I think) and a Honor Guard Wraith Tank with gold trim, I think for Halo Wars. lol I honestly don't know, I just got the cards for free from work, and I only want the 48 hour trials for them, so I figured I should give them away for someone to use.
Honor Guard Tank codes:
1) b7ycv hrpkd vcbgd vf3h4 tymcw
2) g3vx8 yhhgj jw7rv 7ccxc vjvdq
3) kkytv qcggx ycv9c p7g83 y8gqw
4) vx6p8 km2bg d6tjp b2v2f cw6wj
Multiplayer Map codes:
1) tdfqb gx693 8wttd gxr9q rvpd8
2) hgf34 29gm4 3vxd6 kw9t8 yyxcd
3) xc9dc m7r9h 99g9h tvb9t 6qxjw
4) rjm2d drh9j r89mj 4p9df t6g3j
Please let me know if any of them work, I'm sorry if none of them work though, it's like teasing someone with a cookie.
