Batman: Arkham Origins Blackgate - Deluxe Edition

This achievement is missable.

The perfect area will be at the bottom level of Administration when helping the Warden deactivate the bombs. You’ll jump a gas-filled gap when you’re surrounded by generic thugs and thugs with body armor. Try to cape stun everyone but be cautious with the ones is behind you. Use to counter if necessary. Here is a video on how to do it (special thanks to user Survivor Seven for the location).

Note: This is the only time a combo above 100 can be attempted. If you fail to reach 100, just restart the checkpoint.
