So lets' say that you just got the game or you're just looking for some spice because you already chose to have peace with the humans.
If you just got the game: Play the game first! Instead of looking at guides like this to get every achievement (Me)
If you're looking for new stuff: I have a treat for you!
Okay, enough blabberin'. Let's get this done!


THIS IS WHERE THE GUIDE STARTS
There are some prerequisites before this point:
YOU MUST HAVE CONNOR BE A MACHINE If Connor isn't a machine, this interaction won't occur, as instead if Connor were a deviant, he would be at the Cyberlife Tower. You can choose weather you want to become a deviant, or stay a machine in the previous chapter: Crossroads.
Next, you must choose the path of the Revolution. You can choose this at the previous chapter. Then complete all of the levels.
If you did this correctly, and you also did the attack coordination correctly, you will see Connor as he aims at Markus.

Now you have a choice, you can control Markus or Connor. Basically saying: Win the Revolution, or complete your mission.

Once you made your choice, follow the QTEs, and get an outcome.

Outcome 1: Markus Win, Control Markus
This is probably the most common win for Markus, as all you have to do is to complete all the QTEs. The result is Markus destroying Connor.
Outcome 2: Markus Win, Control Connor
This is less common, so listen up. If you control Connor and fail all the QTEs when you have the gun, Markus kills you.
Outcome 3: Markus Win, Control Connor
This ones pretty uncommon too. As you need to fail all the QTEs as Markus is wrestling you on the sandbags. Fail all of them, Markus kills you.
Outcome 4: Connor Win, Control Connor
This is a little rarer, so all you need to do is succeed all the QTEs during when you have the gun.
Outcome 5: Connor Wins, Control Connor
The most common when you're controlling Connor, if you have this one, you probably missed 1 QTE during when you have the gun.
Outcome 6: Connor Wins, Control Markus
There are many ways to lose to Connor as Markus. If you fail all the QTEs when Connor has the gun, you die!
Outcome 7: Connor Wins, Control Markus
If you fail all the QTEs as Connor is on the ground, you die.
Outcome 8: Connor Wins, Control Markus
Fail all the QTEs when at the Sandbags.

As a result, Either The Revolution succeeded, or Connor acomplished his mission.
This is my favorite fight scene in the game.
Thank you for reading this guide.
