(adsbygoogle = window.adsbygoogle || []).push({}); I lost my progress in veteran campaign because I replayed an old level. I was just wondering if i will get the achievement for Completeing Campaign on Hardened or Veteran by going though and beating all of the missions i haven't yet beaten on veteran without starting the whole campaign over again.

I would imagine so mate. I downloaded a modded game save to have some fun on before i completed the game; the level with the mods was one of the final ones (Where i was not yet up to), but as i finished that mission and the rest of them i got the Right achievements for them, and also the complete the campaign on Veteran achievement even though i was missing several achievements from missions i had not yet done.

Cut a long story short, i think the Campaign achievments trigger when the last mission is finished, regardless if missions have been missed out
