Getting to the Alex Mercer's place

Notice! Although it is the last game mission, you do not have to prepare for it in special way, because after completing it, you'll be able to continue playing in Free Roam mode!

In order to start this mission, you have to get to location [534, 94]. Your target is the rooftop of one of the skyscrapers and after approaching your destination, the game will display a cut-scene with Mercer.

First some important information about the final fight with Alex Mercer:

• The duel is divided into three parts and at the end of the first and second part, Mercer's and Heller's energy bars are regenerated.
• In each part of the fight Mercer uses different powers. In first part he uses Blades, in the second one he uses Whipfist and in the last he uses Hammerfist. You can't use the same power as a boss in particular part of the battle, because he will be resistant to such attacks. So I suggest choosing the powers at the beginning of each phase of the fight, especially that holding LB button stops the time.
• You can't leave the battlefield so carefully monitor your energy bar.
• During the fight with Mercer you can't use special attacks (Devastator and Pack Leader). As a result you have to rely on standard Heller's powers.

The fight with Alex Mercer - part 1

First, some general tips on this and next two parts of the fight with Mercer. First of all you should know that your opponent is very agile, so you need to master dodging. I do not recommend jumping over Mercer, but instead jumping to the sides.

Mercer performs few regular types of attacks and the most recognizable of them is hanging in the air combined with spikes from the ground. Once you see the boss planning such type of attack, start long jumping, so you won't get hurt.

Now it is time for details. As previously mentioned, in the first part of the fight Mercer uses Blades, so you can't choose that power but rely on others. I recommend most of all hammerfist and the most effective is charged air attacks (screen above). There are three key factor for this attack: Mercer rarely blocks it, Heller automatically targets Mercer (so you do not have to hold left trigger additionally) and it deal great damage on a considerable distance (so you do not have to precisely hit Mercer).

Of course you do not have to use hammerfist only. You might as well perform attacks with claws and tendrils, as well as pick up nearby objects and throw them at Mercer. But such attacks are more risky.

From time to time Mercer should try to perform special charges. Each time he performs such attack, dodge and then run to the boss pressing the key, which icon is visible over his head (screen above).

Keep attacking Mercer until his energy bar is almost empty. He should then make one more charge, described above. Dodge this attack, run to the boss and finish him. The game will display a short cut-scene, after which you'll automatically advance to the second part of the fight. Notice, that energy bars of both characters are regenerated.

The fight with Alex Mercer - part 2

In the second part of the fight, Mercer will be using Whipfist and in my opinion this makes this encounter most difficult. Do not forget that you can't use the whip now and try to block his range attacks if possible, pressing RB button according to the suggestion visible on the screen (screen above).

In order to inflict damage to Mercer, you should still use hammerfist, but as well as air charged attack, you can use standard attacks possible with this power.

In addition to hammerfist, you could use Blades, which were not available in the first part of the fight. These are the best choice when you suddenly find yourself near Mercer and you do not need to dodge or block.

In the second part of the fight Mercer will be using some of the previously described attack, but he will also have two new ones. A first attack is a charge with the whip, which must be blocked with RB button. When Mercer fails to hit you with this attack for the second time, try to counterattack (press the button, which icon is visible over his head). The second Mercer's attack is an attempt to throw at Heller helicopters grabbed with the whip. Do not worry though about this attacks, because it is enough to dodge in certain moment.

Same as with the first part of the battle keep fighting until Mercer's energy bar is almost empty - then prepare to dodge his last charge. After defeating the boss, you'll advance to the third, last phase of the duel.

The fight with Alex Mercer - part 3

In the third part of the fight, Mercer will be using hammerfist, so the main thing is to keep him on distance, reducing melee fight to minimum. Start with the Devastator attack, to get rid of birds attacking you (screen above).

Do not worry, that you are not able to use hammerfist, because you can find replacement with no problems. I suggest whipfist for this part of the fight. Bounce and attack him from the distance with the whip (screen above). Mercer is almost defenseless for such types of attacks.

Same as with previous parts of the battle, you can also use other powers. I do not recommend using neither claws nor blades, but rather attack him with tendrils. This is also the good choice if you want to keep Mercer on a safe distance.

Mercer will again use the "jump" attacks and it works the same, as in the first part of the battle. So every time you see such attacks, just dodge. Do not forget about running towards him after his failed attack and pressing the proper button (its icon is visible over his head).

Fight until his energy bar is almost empty and prepare to dodge his last charge in the fight and to press the indicated button (screen above). After that you'll advance to the final - definitive defeating the boss.

Killing Mercer

Wait until Mercer performs a large jump towards you and blocks it by holding RB button (screen 1). After successful action start rhythmically pressing X button to pull out his first limb (screen 2).

Prepare to repeat those actions, so block boss's attack (RB button) and pull out Mercer's second limb (rhythmically press X).

The last sequence is slightly different, because in addition to hold RB button (screen 1), you have to rhythmically press Y button (screen 2).

At the end, according to instructions shown on the screen, rhythmically press X button.

And that's all. Have fun watching the last cut-scene and do not remember that after credits you can keep exploring the game world (or start a new campaign in the New Game Plus mode).
