Right, Right, Left, Down, Up, Up, Up, Down - Unlock Body Surf Ability

"Half-Truths" Trophy
Description: 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 will not alert the military as they have their hands full already.

"The Butcher" & "Speed Bumps" Trophy
Description: To easily get "The Butcher" Trophy, 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.

"Trail of Corpses" Achievement
How to: 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.

Orb Collecting XP Rewards
Description: You will 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.

Landmark Orbs

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)

Hint Orbs

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)

Flourish Move
How to: 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.

Web of Intrigue Targets
Description: 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.

Final Boss Strategy
Description: 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.

"Butcher" Achievment
How to: 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."

Smooth Landing Speed Boost
How to: 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. *** This doesn't
work for the highest of drops.

Collectible Vision
Description: It's sometimes difficult to spot Landmark and Hint Collectibles. Switch on your Infected Vision (or Thermal Vision) to help discern them.

"The Cleaner" Trophy
Description: "The Cleaner" Trophy 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.

"Misconception" Achievement and EP
Description: 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 specified 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 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 will have a free tank. *** 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.

Platinum
Earning a Gold in every event unlocks Platinum Events, which are more difficult.

Water Disguise
How to: 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 will can then escape unnoticed.

Mind the Crows
Description: Infected water towers are always circled by squawking crows. This makes it easier to track them down

Secret Story Event
How to unlock: Complete all Scientist Consume events to reveal Karen Parker's location after her disappearance.

Hard Mode
How to unlock: Beat the game on Normal to unlock Hard Mode.

New Game +
Once you beat Story Mode, you will be able to play through it again with all of your powers and upgrades.

Body Surf
How to unlock: To unlock a new ability called "Body Surf," navigate to the Cheats menu (under "Extras" in the Main Menu) and enter this code: RIGHT, RIGHT, LEFT, DOWN, UP, UP, UP, DOWN

EXP Exploit
How to: If you are just short of an upgrade (e.g. you have 90k EXP and you need 100k), you can earn the amount you need, purchase an upgrade with EXP, and kill yourself and return to a checkpoint and you will have both the upgrade and the 90k you had at that checkpoint.

Unlimited EP Exploit
How to: On mission 22/31, where you get the first cell phone cut scene, you will 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 do not 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.
