With the shift blade just keep performing the X X X Down X combo and keep them in the air.Guide not helping? View 3 more guides for this achievement.Leave a comment
7 0 0after you unlock the "arsenal"X = uziY = Shotgunjust wait till a regular enemy jumps towards you and keep hitting "X" 2/3 times every second. Dont mash it. pause between every 2/3 taps for a moment and then tap again.
3 0 0If you don't want to play arcade mode to unlock this achievement, you can connect 2 controllers, then when a enemy is in air keep mashing X with both controllers.Sorry for my bad english, but this does work.
