Assassin's Creed: Freedom Cry

You can only unlock this trophy in the final memory, Memory 9 - de Fayet's last stand. See below for more details. It is also an additional objective in the same memory that must be completed in order to obtain 100% synchronization.

For this trophy, you must disarm de Fayet and attack him with his own weapon i.e the branding iron. Once you locate him in his compound he will run towards the beach, stay in pursuit along with the numerous guards tailing you until he comes to a stop and starts to fight you. You will need to be unarmed in order to disarm him, as if you have your machete or hidden blades drawn you will only be able to attack and not disarm him. To disarm him, you must counter his attack by pressing and then press . Once you have done this, the final cutscene will trigger and the trophy will unlock.
