If I complete the game on a higher difficulty, will it unlock completion achievements for lower difficulties or should we have separate playthroughs for each difficulty?Posted by VindRaider On 17 Jul 20 at 09:56 more than likely separate playthroughs for each difficulty!Posted by Wwau On 17 Jul 20 at 12:24 Update: I just finished the game on "Marksman" difficulty and it automatically unlocked the lower "cadet" difficulty related "Mission Possible" achievement.Posted by VindRaider On 26 Jul 20 at 10:01 Leave a comment
