An idiot-proof method! Requires no skill, no extra equipment. Takes 15-20min.In short
, I'm utilizing stage transitions
in practice mode
to boost combo counter.
Launch Practice mode. (Main Menu>Single Player>Training>Practice)
Starting with Bats, pick each character in rotation. Be methodical. Keep track.
Opponent doesn't matter. By default it's Joker.
Choose stage "Fortress of Solitude" (right column, second row)
Back your opponent to the right corner by forward dashing (mash d-pad/l-stick towards).
Once relatively close to the edge, hit away+heavy (d-pad left+A by default).
Watch the transition mini-cutscene, note combo counter in top left corner (next to health)
Once you see the damage % being displayed under the combo counter, you're good.
Go back to player select, switch fighters, repeat. Easy!

Some level transitions (i.e. Insurgency's) rack up 10+ hits. If you feel like multitasking keep switching chars and stages to combine this achievement with
It's possible to work on 2 characters at a time. Keep rotating both P1 and P2. In match, go to Start>Practice options>Control character #2. Thanks,Pyroloveridge
