Once you purchase the Whipfist Power, you should be able to buy the Sweeper power for it, or whatever it's called. Once you have that, you can hit X-->Y to make Alex swing the whip in a sweep-like attack. The longer you hold Y, the more complete of a Circle Alex will do with the attack, and the more power and range it will have. To get this, simply plop down in a group of infected civilians and charge the sweep to maximum. Try this on a few groups until you get 15 with one attack.

This is simple. To consume a character, as you most likely know, hit B to grab them, and then hit Y while standing still to consume them. This will give you health. I don't know if they count towards the achievement if you have full health when you consume, but you should get most of this during the Elizabeth Greene boss battle, as there are large mobs of normal infected on the side streets, and Greene can hurt you really bad, really fast, but because she's stationary, she can't follow you to the side streets, so just run there and consume when you need to during the fight, and you'll probably end up eating 50 or more characters on average. Continue to do this until you hit 200.

You don't even really need to have the game tell you about the upgrade menu to do this. After your first mission, you should gain access to it, and you'll have a few evolution points, so you can probably buy something like the Overroll for 100 EP. That unlocks the achievement.

This is a little tricky, but once you get the rythm, you'll get this pretty quickly. Progress through the story until you gain the skill to pilot helicopters. Now, buy the Whipfist and the B grab move with this whipfist, and use this to grab the helicopter and pull yourself towards it and then hijack it. From there, kill 20 helicopters without having yours destroyed or without leaving the helicopter. Use the missiles (The third weapon) and shoot from a distance. If they're chargin at you and far enough away, lock-on with LT. The missiles should take them down in one shot. Once you run out of that, switch to the rockets (Second weapon) and lock-on and shoot them from medium range and they should go down fast. Once you reach 20, you get the achievement.

Later on in the story there are several missions where you need to work as the Military. As long as you don't change forum, attack them or use your powers you will get this achievement

Once you get far enough into the game (After you rid yourself of the parasite) you'll gain an upgrade you can buy called "patsy". Now, get a military disguise and go into a base. Lock onto any soldier, hold RB, and hit X when you're close enough. You should grapple him and throw him before accusing him of being you. Shortly after, the rest of the military there will reduce him to a red puddle of crap. This move takes some time to recharge, so just hang around the base until it recharges, and do it over and over until you reach 5.

Progress through the story until you get the ability to drive tanks. Now, get a military disguise and find a tank. When in the military disguise, you should be able to hijack a tank without anyone being alerted. Now, find a busy section of the street (Preferably outside of military zones and infected zones) and start driving on the sidewalk. Be careful not to run over military troops. If that happens, you won't be noticed right away, but they'll get suspicious. Run over too many military, and they'll attack you. Stay out of the infected zones too. Hunters can take your tank down pretty quickly. Now, just drive over people on the sidewalks until you hit 500. If your tank is destroyed, the counter is reset, so be careful.

Go after the Hives as a Military personal. It's easier to destroy the hives as there is tanks, weapons and helicopters to use.

This achievement is interesting because while military vehicals count towards this, regular civilian cars farting around in the street count too. Just go to a non-infected and a non-military zone, pulled out the hammer fists, and start smashing everything. It'll take a while, but you'll eventually hit 2000.

One of the most fun achievements ever. Get in one of the smaller tanks, and just unload on a busy sidewalk with both weapons. If you get enough people, you unlock the achievement.
