Mafia III: Definitive Edition

Story related, cannot be missed. This trophy is for completing the final story mission of this DLC.

This final mission is pretty long and is basically just a lot of massive enemy fights and 1 boss fight. You will go through the entire army base, killing enemies as you go. Near the end, you will descend a silo into a submarine base (this is where the boss fight is). The boss has tons of enemies that seem to keep spawning indefinitely and you have to take him out while he fires a very powerful turret at you. To kill the boss easily, head up the stairs on the right. Grab the RPG up there and shoot him once, then take out the rest of the enemies. Once all the enemies are dead, you will get a prompt to enter the submarine. Watch the cutscene and Aid and Comfort will pop afterwards. Next, you will enter a truck and leave the base before being ambushed by 1 final set of enemies. Take them out to survive the ambush, then watch the cutscene.

The trophy will pop after the scene is over.
