I am planning to replay a campaign (to achieve other achievements). Will I be able to see the results of the previous one?
For example, one of the achievement is: to accomplish all 29 mission while one campaign "line" contains only 26. How could I know which missions should I pass then?
Best Answer
Achievements are carried over between playthroughs.
If you start a new campaign, no achievement data will be lost.
However, in your case specifically, it is also possible to replay the 3 missions you didn't do the first time via the battle archive available on the Hyperion's bridge.
