I've tried this and I've found a problem with it, 1 the guys stopped jumping to their deaths at 12 not 11 sadly, but beyond that, I ended up with not just shotgunners and machinegunners, but also pistolers and hand cannoner too. revising this, you should bring in a shotgun and a pistol, cause on the first blimp thing there's 2 pistoleers which should be all of them, and shitloads of shotties, when they're all dead you can jump on that blip and grab the hand cannon and machinegun.
Easiest way to do the challenge (13?) where you kill enemies with their own weapons is... you don't. I can confirm through experience that you can just use Undertow on them and throw them ALL off the map. Also you supposedly do not need to do the fireman challenge (can not confirm), but it is easy if you just get a fireman near suicide and undertow it along with two normal enemies. The undertow method doesn't seem to be posted anywhere though, so try to spread the word guys.
use this, easy just complete the last wave whit shotgun, ITS NOT MY SAVE, i take this from 360haven thanks to Citc http://www.mediafire.com/download/f78aflj4gjokbfq/Bioshock+Infinite+%28Citc%29.rar
Is there a save that pops the wave achievements too? I'm fairly bad at shooters and the waves are just killing me.
Thanks man this really helped, I was just short of pulling my hair out trying to do this achievement.
