Easy Thermobaric Tank
First you must unlock the Kill Event called "Rolling Thunder," which appears between the
and the East Village 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
Easy "Half-Truths" Trophy
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" Trophy
"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.
Easy "Misconception" Trophy
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, and fire away.
Easy "The Butcher" and "Speed Bumps" Trophy
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.
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 collect 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.
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."
Mind the Crows
Infected water towers are always circled by squawking crows. This makes it easier to track them down
Start a New Game Plus on a different difficulty
After unlocking the New Game Plus option for Easy Mode or Normal Mode, it is possible to start a new game plus on a difficulty setting for which it has not been unlocked. To do this, under New Game, select Easy plus or
Normal plus, whichever
is applicable. Instead of saving as prompted however, press circle to back out
of your selection, and then select a difficulty for which the New Game plus has
not been unlocked. Save the data when prompted to begin the game. You will
begin the game with New Game plus status, without having unlocked it for the
corresponding difficulty setting.
