Note: This trick requires that Batman is fully upgraded with all combo-based upgrades, etc. This is easily done in the later rounds of the first Challenge, "Intensive Treatment". You must perform the following moves in a single combo, without getting hit, blocked, or allowing the combo counter run out: Quick Batarang (may be optional), Quick Batclaw (may be optional), Punch, Stun, Evade, Counter, Throw, Instant Takedown, Ground Takedown. Note: You can evade as many times as desired to maintain the combo. Start with the Batclaw and follow up with a Batarang. These may not be required, but you may as well throw them so they cannot hinder you. After using the first couple moves listed after those, plus a number of Punches to get your combo meter above 5x, you can perform a Throw. Do not let Batman hit anyone else or you may leave yourself without any opponents to continue the combo. Punch a bit more and Evade as needed, then use the Instant Takedown when becomes available. Before using a Ground Takedown to complete this combo, use some Batarangs to stun anyone else nearby. If it is all clear, execute the Ground Takedown to complete the "perfect" combo.
