Tips

How to avoid dieing from running upside down

Sometimes when you are low on health and try to run up a building you find that your running up the front door and upside down which then get's you killed by the Blackwatch. To stop this from happening, when you hit the front door you must let go of the R trigger and move away and press it again quickly to dash away.

How to earn fast EP (Evolution Points)

Later in the game, the infected areas are quite large and many infected civilians are ripe for the taking. Devour as many infected as you can and in doing so you will earn EP.

Also there is an alternative but it is very time consuming and can get frustrating. When you are not in the infected zones, cause as much havoc as you can so a Strike Team is inbound. Then you must hide away from them until the Strike Team is gone. You will be rewarded with 20,000 EP.

Quick EP points and Easy Misconception Achievement

It's best to do this AFTER you have acquired the Infected Vision. Look for either the "Friendly Fire" or "Projectiles" Kill Events as both have helicopters sitting next to the Event markers. Jump into the helicopter will bring up the event requirement screen, but simply leave the event by pressing B. With your new helicopter at your disposal, activate your Infected Vision. Target and destroy infected water towers (around 8-10 machinegun rounds or 1-2 non-homing missiles each) for between 8,000-15,000EP each, other helicopters (about 12-15 machinegun rounds or around 6-9 non-homing missiles each) for about 20,000-35,000EP each, or Hives for around 30,000-40,000EP each. The helicopter is equipped with 600 machinegun rounds, 220 non-homing missiles, and 14 homing missiles.

Destroying 25 infected water towers before they hatch couldn't be any easier and the mass amounts of EP points you'll get from a single helicopter is a major bonus.

REMEMBER: like my Thermobaric Tank hint, if you leave the helicopter it will vanish back to the Event marker. Also, if you destroy a Hive or Base, it will RANDOMLY vanish. I've taken out anywhere from a single Hive to 6 compounds (4 Hives and 2 Bases) before it has vanished on me. Be prepared to run just in case.

Glitches

UNLIMITED Thermobaric Tanks

As the game progresses, various Events will unlock to be played at your choice. A certain Event to look for is a KILL Event called "Rolling Thunder" (I just finished mission 22 but the Event may have been unlocked before then). It will be located between East Village and 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 simply hit the "B" button to back out of it. Now you have the most bada** vehicle in the game! The catch… if you exit the tank it OR if you use it to destroy a HIVE or BASE it will vanish, but only back to the Event point. Happy hunting!
