So I've saved the hardest for last. And was wondering what's the best way for leveling air stomp. Also for you people who have already maxed air stomp what's it do. Unsurprisingly to me I've never encountered anyone with it maxed.

I'm in the same boat with the same questions. I'd really like to use it, but I can't aim it and it doesn't damage squat for me. I'm hoping level 3 of it is what I want... if I ever get there.

I played Crash Site solid for about a week - it is a long hard road though - get used to jumping blind and crossing your fingers! Level 2 lets you ignore all fall damage and Level 3 lets you recover faster from the stomp. I only really levelled it to get the Armour Dog Tag and dropped the module when I maxed it out - it gets very frustrating, but when you do get a kill with AS then it fells great!

In my journey to max it out I managed to get one triple and 5 or 6 doubles.
The best Crash site maps for Air Stomping are Pier 17, Wall Street, Parking Deck & Skyline.

The trick for using it is that you need to land facing the enemy - the area up to 6 feet in front of you seems to do more damage (a bit like the Gravity Hammer in Halo:Reach if you ever played Grifball). If you land to the side of someone then the Air Stomp is not as effective. Good Luck!

i've recently reached lvl 50 and got about 12 AS kills, most of the time i screwed it up and got owned while trying.lol
but it's pretty satisfying if you get a double kill, so i'll keep going on!:)

I got stomp lvl 3, rebooted and now I have it at lvl 3 again in just 3 days, and 80% of my games are IA, don't just looking forward to lvl it up on crash site only, you can use it anywhere.

I have a small trick for you: shoot your target a couple of bullet but don't kill him, them just hop and stomp, that's a 100% kill, and whenever you think your target is low on health, don't hesitate and stomp, I do get an MVP in 80% of my IA games with less than 10 death, sometimes no death, so that mean I'm not a stomp camper who wait for people to come under me, I actually run around and look for them, always stay in high places and use your sense, I got at least 1 stomp in almost every match no matter what map or game mode and my best record is 8 stomp in 1 match, which is quite satisfying XD

Once you've learned how to do it properly, you will love it, I never want to use energy transfer again because everybody is using it, good luck with you stomp grind!!!

what you need to do is move around in high places and sneak up behind where you think the enemy(ies) are cloak and take them by surprise they won't know what kicked there asses. Btw in the Crysis 2 mp demo i got 54 airstomp kills one was a relentless(quad kill)
