Batora: Lost Haven

During quest With Great Power you’ll talk to the chief then Mila presents two options - choose “I will fight the army” and play through to complete the mission and this will unlock. Another choice is offered in the quest for Thor or Sven - I chose Sven and this popped while CrmsnsShdw (thanks in comments!) chose Thor and it also popped.

There will be two auto saves calling Turning Point - load the earlier one to choose the other route to get the other missable achievement “Last Will”.
