Tough Nut is an achievement in Mafia II.


Finish the story on Hard difficulty level.


On hard, your health takes the most damage and regenerates the slowest, and you can easily be killed in one or two shots. In addition, enemies are no longer visible on the HUD radar display. Stay in cover and take your time. Not knowing where the enemy are is the most difficult part, so watch for Joe to advance forward, which will indicate everyone in the immediate area is dead.
