For Honor

As with all PvP based achievements there is a bit of luck and patients required.

To do a aerial kill you need to go to a ledge and stand over it, your character should lean forward and look down, when doing this hit RT and you will leap down and attack. There is a bit of leeway when doing this, as they do not have to be directly beneath you to kill them, but they do have to be pretty close.

The way I knocked out a lot of these is by playing Dominion on the map High Fort. Once in a game I would go capture point A and basically camp there. On the side of the tower with the hole, facing C there is a ladder that people like to climb up to A. Simply wait for people to come up to the ladder as they are climbing do an aerial kill, as it still hits people who are climbing ladders. Once you start killing just climb back up the ladder and rinse and repeat.

You can obtain this achievement on every map (I believe) this is just how I got a majority of my progress for it.

If you think there is anything wrong with this solution please leave a comment.

Happy hunting!

This can be done very easily on the Overwatch map, simply because the kills can come from Heroes/players and infantrymen/grunts. Do this during a Dominion match, Overwatch map, stand on either bridge above Zone B and wait for an infantryman/grunt to run under you or a Hero/player and hold RT to drop on them.

This will take a toll on your health, so just run back to either Zone C or A and if it's already captured heal yourself. If not, capture the zone heal yourself and run back to the bridge and do it again. Just keep an eye out for other players creeping up on you and tossing you off.

This achievement can be done on any map, but this one I found was the quickest and easiest way.

I found the Dominion method takes too long and is mostly luck based. As per my video I found playing Brawl 2 VS 2 on river fort to be a quicker and easier to control your opponent. Please note the second clip in my video is filled with Bots due to everyone lagging out but me, the kills that I got still counted towards the "heads up" achievement.

For the easiest way to obtain this you have to be playing Dominion on the new map named Sentinel that came along with the 3rd season of the game.

I found a very easy way to obtain this achievement. All you have to do is go to either capture point A or C and start using the ballista's that are aiming towards the middle. Aim for the group of soldiers that's fighting in mid, eventually also kill enemy heroes.

I started this match with 16/25 and so it took me 1 kill from above before discovering this little trick. So it took me just a couple seconds to obtain my achievement.

Enjoy your achievement and have fun out there! ;)

Not entirely a solution as it is PvP based.

But using this tactic was netting me at least one kill from above per match.

Play dominion and always vote overwatch when you can.
Hang around the high bridge areas. Keep an eye out for fights below on either side. There is a good chance you'll be able to land on someone and kill them.

*Note press Right Trigger on a ledge to perform this kill.

You can just throw a fire bottle on a group of minions. I did this on Sentinel and killed 33 minions with the fire bottle. The achievement popped instant.

The first method above DOES work but, you can't sit over the ledge and make it completely obvious that those are your intentions. Try to sit back a little bit then rush to the edge and attack. Might take a few tries to find the farthest distance that you can push the attacks because even if there isn't an enemy below in range of your attack, you can still attempt the attack and possibly killing yourself.
