The new ODST achievement states "kill an enemy player while in the air from a man cannon" I got it last night in a game on shatter. Theres something wired about it tho. I ran up and killed an enemy then tossed a grenade right before i was going to die and jumped backwards then got headshotted. while i was dead in mid-air my grenade detonated and killed the guy from the grave and the ODST achievemnt popped up on my screen. I was not near a man cannon plus i dont even think that map has a man cannon. So is it glitched? i didnt save the clip cause i didnt think anything of it at the time but now i wish i did.

i've heard many people get this on maps that didn't have man cannons

Both Kobe and I got it last night doing exactly what it doesn't say. Its glitched...

I was in the mantis and got PP'd, and there were 2 enemies trying to board me so I got out and threw a grenade at the mantis. I died in the explosion along with the enemies, and then got the achievement!

I got it while jetpacking... well, while I was falg from a jetpack.

I got it while jumping, I think it's just attached to being in the air at the time of the kill.

I think a buddy of mine got it when his hog exploded, killing him and his assailant. Also on a map with no man cannons.

All the crimson maps have mancannons(ie lifts at least). But yeah, it seems to pop up when jetpacking. Ahh I keep laughing at all the players running around like chickenheads with turrets on shatter. hehe
