Mass Effect 3

This achievement requires the player to personally lift or knock an enemy into the air with a power, such as Singularity or Concussive Shot. Squadmate powers will not count towards this achievement, even if you order them to use the power.

As long as the enemy's feet leave the ground, it'll count towards the achievement. Powers that will work are Singularity, Pull, Throw, Lift Grenade, Concussive Shot, Biotic Charge, Carnage* and Overload*. I've been told that Slam (DLC power) will not work even though the enemy is technically lifted into the air.

As with most other achievements in the game, you can continually reload your save to get the lifts using the same group of enemies. These will count across both single-player and multiplayer combined, so getting some in SP and some in MP is fine.

*Once they are maxed out.

Don't want to reload a save over and over again? Don't want to inconvenience an online team with your constant use of Throw? Can you stomach the opening scene of the game again?

Start a new playthrough as a Sentinel. Change the difficulty to Narrative. You'll begin the game with Throw (that recharges within a second). *I did import a Level 30 ME2 Shepard. I'll have to confirm on a brand spanking new Hero.*

Start the game and go through the opening scenes where everyone realises they should have trusted our famed hero. Nothing like massive reaper death in an afternoon to help you re-evaluate your trust, eh? Get to the part where you meet the dying idiots on the ground who tell you to get down before you're seen (the shouting at you wouldn't give your position anyway or anything, right?). The game will insist that you press A to take cover but give the game the finger like the ending did to you and stand upright. Away from cover. You're a rebel, enjoy it. Screw you game.

This is where you'll get the achievement in less than 10 minutes. As long as you don't go to cover, Cannibals will spawn endlessly (up to 3 at a time). Press RB to use Throw, kill the enemy with your pistol and move on to the next. You cannot use Throw multiple times on the same target or it won't count. As a rule of thumb, if you've hurt it, you've thrown that fat little bugger.

As you are on Narrative and there's unlimited ammo pick-Ups, you'll never die or run out of ammo. Just aim a little above each enemy to send the power over the railings.

If you haven't got 5000 kills yet, this is a fantastic place to do so, but that's your decision to make, not mine. No indoctrination techniques from this guy... You will worship me... Nope? Damn.

EDIT: DakotaThrice has an alternate character class; "Imported a Vanguard from a previous games and used Biotic Charge. The recharge isn't as quick but the method works just as well"

you can also get it in the dlc Citadel in the combat simulator

Lift 100 enemies off the ground with powers.
Overload the shields of 100 enemies.
Kill 100 enemies with melee attacks.
Perform any combination of 50 biotic combos or tech bursts
Kill 10 guardians with headshots from the front while their shields are raised
Set 100 enemies on fire with powers

i did 3 already using the combat simulator and they counted.

so if yo are missing some of like me dident got the 10 headshort in the rest of the game you can get them there also.

yust put it on easy only you so your teammates dont get the kill and keep playing the level till you get the achievements you want

I just got this shortly after reaching Mars. On Earth, I used Throw on every enemy I saw, even using it while they were on the ground. When I reached the part when you use the radio, i continuously hit the enemies with Throw, not firing a shot and they just kept spawning. I was able to get 70 of the enemies in the air by the time I'd finished Earth, the other 30 I got shortly after reaching Mars.

Not sure if it was a glitch, but it worked for me, so let's hope it works for you guys.
