Note: You can most likely do this trick with any helicopter. Do 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 the areas. You get about 8,000 experience points for each. Shoot 25 of them and you will get the achievement or trophy Xbox 360 PlayStation3 for killing 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 this is going on. One water tower requires one missile. Make sure to steady it so you do not waste missiles. One flythrough with this helicopter can net 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 only works once you acquire the ability to hijack helicopters and have Infected Vision, received later in the game. Hijack a helicopter. Once you do so, activate Infected Vision. Look for the bright orange water towers scattered throughout the level, primarily in the Infected areas. Shoot them with the helicopter's weapons. For each water tower you destroy, you will receive 10,000 experience points, which are important this far in the game. Note: Water towers respawn continuously for unlimited experience points.
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 with a direct hit. You will receive 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, destroy forty more 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 amount of time.
Defeating the Time Square Boss
Contrary to popular belief this Boss battle is easy. Long before the battle, purchase all upgrades that allow you to do +3 Devastator attacks, upon max health. It is also a good idea to get all the upgrades you can via "Consume". The Boss is massive. Notice that under her life bar are other bars. These are some what 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 have to do. 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, though with the upgrades one hunter can nearly boost your life to max, allowing for maximum Devastator attacks. This is one of your first Devastator attacks you will learn. Scale a building, boost over to her, fall, and initiate the attack. You will see quickly that the Boss' stabilizers are being damaged. Note: Every round the stabilizers' life 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 done, she will fall and you can attack normally. She will then retreat (leaving you plenty of red life orbs to consume) before shooting out of the ground again, with more stabilizer life 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.
Defeating the Final Boss
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.
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.
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.
Finding Infected Water Towers
Squawking crows usually circle the Infected water towers, making them easier to find.

Unlimited EP Exploit
On mission 22/31, where you get the first cell phone cut scene, you'll be asked to jack a Black ops helicopter. Once you have the helicopter, you are prompted to pick up a few Black Ops guys and then destroy a Hive. Do not destroy the Hive!
You now have a helicopter with unlimited missiles, no time limit, and as long as you don't destroy the Hive, you can blow up anything else without it kicking off the alert meter. This also allows you to get out of the helicopter without it ending the mission (useful for collecting Memory Strands).
The easiest way to get EP in this is to switch to your Infected Vision and fly around blowing up infected water towers. You can save your game in the middle of this mission if you need a break and do the same thing. You can max out your skills and then some using this exploit.
It's sometimes difficult to spot Landmark and Hint Collectibles. Switch on your Infected Vision (or Thermal Vision) to help discern them.
Mind the Crows
Infected water towers are always circled by squawking crows. This makes it easier to track them down.
Smooth Landing Speed Boost
After jumping, avoid using both of your dashes while airborne and save one to use just before landing. If timed correctly, you should hit the ground at near full speed, which is very useful when attempting to evade the military or during a timed activity. Note: This doesn't work for the highest of drops.
Easy "Butcher" Achievment
Once you've attained the Critical Mass and Tendril Devastator upgrades, simply choose a disguise (in order to keep a low profile), walk into the middle of Times Square, wait until you are surrounded by people and unleash the Tendril Devastator this will land you "The Butcher."
Final Boss Strategy
After the cut scene ends, quickly switch to Armor and Blade (Infected Vision also helps). Stay away from your opponent until he starts to jump after you. When he lands, hit him with the Air Blade Slash. Get in a couple of good hits and he should be stunned. Grab him and repeatedly hit the PUNCH button. If he knocks you down to critical, use a Devastator move to stun him.
If you are near water, and the military is everywhere, then hop into the water and change your disguise immediately as your entire body enters in the water. You'll can then escape unnoticed.
Web of Intrigue Targets
Most of the WoI targets will appear randomly, usually while doing a mission or a side mission. But the last few will pop up randomly. It takes forever, so grab a helicopter (using the mission-canceling exploit above) and use it to fly around the city to make things easier.
Orb Collecting XP Rewards
You'll receive XP for each Orb you pick up. That value is based on how many Orbs you've collected. These values are given below in addition to the one-time bonuses you get for reaching certain Orb collection milestones.
1 - 2,600 each
10 - 5,000 each (+10,000 bonus)
25 - 9,750 each (+25,000 bonus)
100 - 15,000 each (+50,000 bonus)
125 - 17, 250 each (+60,000 bonus)
150 - 20,000 each (+70,000 bonus)
1 - 5,000 Each
10 - 7,500 each (+10,000 Bonus)
15 - 12,500 each (+25,000 Bonus)
35 - 15,000 each (+50,000 Bonus)
Once you purchase a power in Prototype and have it set as a shortcut move, you can then hold down the shortcut button to do a flourish move with the power. It's a unique, if useless, animation.
Easy Thermobaric Tank
First you must unlock the Kill Event called "Rolling Thunder," which appears between the East Village and the Lower East Side (one block from the East coast). Right next to the Event is a Thermobaric Tank. Jumping into it will activate the Event, but you can back out of it before the Event begins. Do this correctly and you'll have a free tank. Note: If you exit the tank it or use it to destroy a Hive or Base it will vanish. You can grab it again at the Event point.
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 "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 "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 "Misconception" Achievement and EP
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.
Later in the game this becomes even easier. Just hijack a helicopter, fly over infected areas and keep tapping the target button until you target a water tower (or helicopter or Hive) and fire away.
The "Friendly Fire" and "Projectiles" Kill Events as both have helicopters sitting next to the Event markers, so grab those and exit the event for a free 'copter.
Easy "Trail of Corpses" Achievement
Using the Thermobaric tank cheat described above, simply circle the hives of infected and fire at the people. Each shot can usually take out 50+ people. Infected Vision is recommended.
