Trophy Description:A duel between rivals.
Bronze Trophy.
*Missable trophy*

At the very end of Mission 6 "Karma" you can either go after DeFalco and catch him, or wait until he is gone. For this trophy you have to let him flee. Do not go after him, just wait for some while before you move to the last checkpoint.

In Mission 8 "Achilles' Veil", during an interactive cutscene you can decide whether to kill Harper or Menendez. Kill Harper (but be quick, if time runs out Menendez will shoot you)! You are not allowed to complete the Strike Force Mission "Second Chance". Keep playing until you meet Briggs during Mission 9 "Odysseus". The trophy will pop during a cutscene. You may not skip any chapters in between these. If you've missed any of these steps, then you can still rewind the story back to Mission 6 in mission selection by pressing R1. However, if you make use of this option you will have to choose "continue story" and play all upcoming mission in correct order again.
