The Truth ending: During the “Identity Crisis” mission, select the “Truth” option to unlock “The Final Countdown” mission as your final mission. Complete the mission to get the “best” ending.
The Ambush ending: During the “Identity Crisis” mission, select the “Lie” option. After lying, run to the gate in the back of the safe house. You must unlock this door earlier in your playthrough to get this ending option. Run to the backroom, and use the radio to call-in an ambush to unlock the “Ashes To Ashes” mission as your final mission. Complete it to get the “Ambush” ending.
The Failed Lie ending: Like the previous ending, choose to “Lie”, but do not use the radio to call in an ambush. In this ending, you will not be able to get revenge since it is over for you. This will also unlock the “Ashes To Ashes” mission but changes the outcome.
