Sea Wolf Achievement
Complete 50 secondary missions
These achievements require that you complete a cumulative total of 10 and 50 secondary objectives. Secondary objectives are the optional requirements for the side missions. Side missions include:
- Assassinations (three secondary objectives)
- Races (three secondary objectives)
- Mysteries (two secondary objectives)
- Merchant Chases (three secondary objectives)
These achievements will unlock naturally when progressing through the game or while going for the 100% sync achievements. There are far more than 50 in the game. Note that each secondary objective can only be completed once to count towards the 50. Once it is completed, it will appear with a green check mark over it on the mission-select screen.
