Attack animations
When consuming enemies, use different attack powers such as the Whipfist or the Blade to see different animations. Each attack power has a few animations to show off.
Better landings
When jumping, use a dash just before landing. If timed correctly and if the drop was not too great, you should land at near full speed.
Body Surfing
Select the "Extras" option at the main menu. Select "Cheats", then enter Right, Right, Left, Down, Up, Up, Up, Down as a code to unlock Alex Mercer's devastating body surfing ability. A message will appear to confirm correct code entry.
Defeating Supreme Hunter
Quickly switch to Armor and Blade after the cinematic ends. Having Infected Vision will help. Stay away from the Boss until he starts to jump. After he lands, attack him with an Air Blade Slash. He will become stunned after a few good hits. Grab him and repeatedly punch. If you are taken down to critical level, use a Devastator move to stun him.
As soon as the battle begins use your armor power and hook power. Immediately begin to use one of the following tactics.
Tactic 1
Keep him locked on. Hold [Jump] for a moment to get reasonable air. As soon as you jump, hold [Attack] button and allow it to fully charge. Then, immediately repeat. This should take four stuns to kill him. Do not bother disguising as the military will barely bother with you.
The first stun
The Supreme Hunter will be stunned very quickly from this. As soon as you are locked onto him and press [Grab], you should hook onto him and immediately be able to begin punching him. Instead of button bashing, press [Attack] at an easier rate than you normally would. It will register more and you will attack quicker. After the first stun, which comes very quickly in the battle, he will finally get the chance to use most of his attacks out on you.
His attacks
Normal Attack: His normal attack is usually swiping at you with his fists and will fling you into the air. These are very easy to dodge. If you are having trouble, try jumping then air dashing away or over him.
Throwing: Around the battle area are several explosive props which he will pick up and throw at you if you are far away. This is rare however, and he will usually miss.
Spike Attack: When he uses his attack, it is a very good idea to jump and double air dash away from him as much as possible. As soon as the spikes have shown themselves, it is useful to run at him quickly and get a few good charged slashes into him with your blade. You should not need to do this until after stun two.
Devastator: This is very easy to dodge. He will stand still and begin to spasm a bit before he unleashes his Devastator. Do not stand close to him during this time, as he can unleash an instant kill on you even when wearing armor. Instead, lock onto him and air dash around him in a circular radius until the main large tentacles have tried to hit you. Once they have missed (there are about three or four of them), find a spot clear of the large tentacles and change to blade power. Begin swiping at him with slightly charged blade attacks. You should be able to get your first hits into him while the tentacles are still moving out and not retracting. You can also get hurt while they are retracting; try not to run into them.
Repeat "Tactic 1" and counter his Devastators when you can. You will eventually stun him for a second time and you should encounter a cinematic during or slightly after the second stun. After the cinematic, you will realize that you have a time limit to kill him. Do not worry about it. Just repeat the first tactic and he will eventually die. You should not need to use "Tactic 2" unless playing on Hard mode or running low on time.
Tactic 2
Wait for the Supreme Hunter to land after a jump and slash him from behind with a few slightly charged blade attacks. As he turns to attack you, jump and air dash over him. You may choose to aerial attack him with a kick or slash him and then jump away. This will lower his health quickly, combined with attacking him during Devastators and spike attacks. This is advised only if you are really running low on time and have just finished stunning and hitting him.
Depending on whether you are still using "Tactic 1" (recommended), you should be able to quickly finish off the hunter within two more stuns. There are four stuns in total. Each stun should take away about 25% of his life under the Medium difficulty setting. If you are using the blade tactic, you will probably encounter him for longer and may get less stuns on him.
Healing
You should not need to heal before the cinematic. However, if you do get hurt badly during the second half and there are no people to consume, either stay with "Tactic 1" and jump kick him, or run to the part of the ship with the turrets (the tower object) and jump behind it into the water. As you jump back out, press Forward against the ship and you should hit the ship while coming back up and fall back into the water. Try to press [Grab] onto the side of the ship and heal there if possible. The Supreme Hunter should not be able to hurt you there. Just remember you have a time limit.
Defeating the final Boss
Quickly switch to Armor and Blade after the cutscene ends. Having Infected Vision will help. Stay away from the Boss until he starts to jump. After he lands, attack him with an Air Blade Slash. He will become stunned after a few good hits. Grab him and repeatedly punch. If you are taken down to critical level, use a Devastator move to stun him.
Defeating the Time Square Boss
This Boss battle may seem hard, but it can actually be easy. Long before the battle, purchase all upgrades that allow you to do +3 Devastator attacks, upon max health. It is also recommended you get all upgrades possible through the "Consume" option. The Boss is massive. Notice that under her health bar are other bars. These are the Boss' stabilizers, making her vulnerable only after you have severed them. At the beginning of the battle she will do a scream attack. Be careful. Scale up a building or whatever else you can. It is very easy to avoid. You will also have Hunters and Infected chasing you. Use the full body armor and claws/blade. Max out your health by running around and consuming. It is easy, and the only issues you might have are Hunters, but with the upgrades one hunter can nearly boost your health to max, allowing for maximum Devastator attacks. This is one of the first Devastator attacks you learn. Scale a building, boost over to her, fall, and initiate the attack. You will quickly see the Boss' stabilizers are being damaged. Note: Every round the stabilizers' health will increase, meaning that you have to follow the tactics in the same way, and it will just take slightly longer. Strike her with the Devastator. You should have a chance for more, unless she does multiple attacks (green orbs that track you, spitting concrete, and screaming). The armor reduces the amount of damage inflicted, allowing you enough time in-between attacks to initiate the Devastator again. Once the stabilizers are destroyed, she will fall, and you can attack normally. She will then retreat (leaving you plenty of red health orbs to consume) before shooting out of the ground again, with more stabilizer health and "backup". Ignore the backup. This tactic works nicely, but if you get low on health, run away from her view, and keep consuming. After she falls a total of three times, you will have defeated her.
Easy "Half-Truths" Achievement
An easy spot to complete "Half-Truths" is the mission in which you lead the Leader Hunter to Ragland. Complete your objectives unnoticed (shouldn't be a problem) until you are prompted to lure the Hunter. Look at the map and notice that it is mainly covered in red (infected zones) and two blue (military) zones, one on the far east and far west. There is an unclaimed area straight up the middle. Stick to this path and you won't alert the military as they have their hands full already.
Easy "Misconception" Achievement
The "Misconception" Achievement requires you to destroy 25 infected water towers before they hatch. Do this after you get your powers back -- when Ragland helps you -- as there seem to be more of them in abundance. Lock on to one and run up the corresponding building, jump to the roof and use the flying kick attack, causing more than half of the life bar to be depleted. Upon landing, follow up quickly with a combo. To make it a little faster, use the "claws" powers.
Easy "The Butcher" and "Speed Bumps" Achievements
To easily get "The Butcher" Achievement, which requires you to kill 50 people in five seconds (including pedestrians, military, infected etc.), wait until you have the ability to hijack a tank. Drive into a red zone that typically has a lot of fleeing normal and infected civilians and stick to driving on the side walk. Keep up with this same tactic to unlock Speed Bumps, which requires you to run over 500 people in a single tank.
Easy "The Cleaner" Achievement
"The Cleaner" Achievement requires you to destroy 10 military bases or infected hives. Choose Hives. Hives are being pummeled by the military by the time you get there, so some of the work is already done. All you have do is finish them off. Hijack a tank and destroy it. NOTE: The hives destroyed during missions count as well.
Easy experience
An easy way to get experience points is to get a helicopter, preferably without alarm. Go to any Infected area, and search for water towers containing Hunters. These are easily found by going to the area where the crows are circling. This indicates where an Infected water tower is located. Lock on to it, and blow it up with a rocket. It should only take one rocket with a direct hit. You will get 8,000 experience points per water tower. With 200 rockets in an attack helicopter, you can get 1,600,000 total experience points. Then using the machine gun, you can destroy forty more water towers. You can then use the remaining homing missiles to blow up a hive for more points. Get another helicopter, and repeat the process. The water towers will respawn after a short period of time.
Play the mission where you have to steal a helicopter to find the right Hunter. You are told to go fly over the Infected area and scan the Infected water towers for a suitable enemy type. Instead of doing that, fly to the Infected area, and start shooting the Infected water towers that are around all Infected areas. You get approximately 8,000 experience points for each. Shoot 25 of them to get the "Misconception" achievement for destroying the Infected water towers without them hatching. As long as you properly hijack the helicopter and no one suspects you as an enemy, no one will attack you while you do this. One water tower requires one missile. Make sure to steady it so you do not waste missiles. One flythrough with the helicopter can get you 1,192,000 experience points, assuming you can find one water tower per missile. You can get even more than that if you use your machine gun. After getting about 500,000 experience points, crash the helicopter, and repeat the process again from the checkpoint.
Note: This trick requires the ability to hijack helicopters and have Infected Vision, obtained later in the game. Hijack a helicopter, then activate Infected Vision. Look for the bright orange water towers scattered throughout the city, primarily in the Infected areas. Shoot them with the helicopter's weapons. For each water tower destroyed, you will get 10,000 experience points, which are important this far in the game. Note: Water towers respawn continuously for unlimited experience points.
Use the following trick to gain more experience while running. Carry an army truck or another large object and run through the infected people, or collect the genetic materials that comes out of a hive.
Experience points for Orbs
The experience points awarded for each Orb that you pick up is based on how many Orbs you have already collected.
Hint Orbs
1: 5,000 each
10: 7,500 each (and 10,000 bonus)
15: 12,500 each (and 25,000 bonus)
35: 15,000 each (and 50,000 bonus)
Landmark Orbs
1: 2,600 each
10: 5,000 each (and 10,000 bonus)
25: 9,750 each (and 25,000 bonus)
100: 15,000 each (and 50,000 bonus)
125: 17, 250 each (and 60,000 bonus)
150: 20,000 each (and 70,000 bonus)
Extended change
Hold D-pad Down or D-pad Up when using the armor power or attack powers to see an extended change in disguise. Each power except for the Vision Powers has their own mini-cinematic. You can test it with or without the armor on.
Finding Infected water towers
Squawking crows usually circle the Infected water towers, making them easier to find.
Hard difficulty
Successfully complete the game under the Normal difficulty setting.
Helicopter jumping
To do this trick you will need the ability to Jump Kick so that you can fly towards the first helicopter of The Strike team. You can also use the Whipfist's Grab upgrade to latch onto an enemy helicopter. Double Jump can also be useful. To start, jump up and Jump Kick or use the Whipfist Grab to latch onto the first helicopter. Do the button event to kill the pilots. Fly up as high as possible and look for the next target. Make sure to use the Lock On ability. Jump out of the current helicopter and Jump Kick towards the next helicopter. You can keep doing this as long as there are helicopters. If you fall, quickly use the Whipfist Grab. Note: This can be very challenging but if done successfully you can attack numerous helicopters without ever touching the ground.
New Game+ mode
Successfully complete Story mode. You can now replay Story mode with all powers and upgrades previously unlocked. Note: New Game+ is only unlocked for the difficulty setting that you have completed (and any lower difficulty settings).

Earn a "Gold" rank in all events. Note: This may also unlock some Radical events.
