I most of the liberty campaign achievements including Kerrigan's reward :} For viking arcade i won it and i have bronze medal. I'm not really keen to get silver or gold since there isn't any reward and it's an annoying game.

For secrets, i unlocked the secret mission from media blitz, and also the cow secret from zero hour.

I also have 3 feats of strength,

- you're so crazy
- the scenic route
- monster mash

I suspect there are more, but no word yet online Obviously i don't have the fan achieve since i don't have the collector's edition.
