Harley Quinn’s Revenge adds 250 gamerscore (or approximately 412 lbs of bronze and silver PlayStation trophies) to a stellar game that you’ve probably already played far beyond completion. We expect you’ll get as much fun as you can out of this DLC chapter too, so we’ve whipped up a guide to help you along the way.
A Few New Tricks
Use 5 different Quickfire gadgets in one fight as Robin in Harley Quinn’s Revenge
You can actually pull this off in the very first three-thug fight of the DLC episode. The moves don’t have to be made in a single combo, just in a single fight. This makes Robin’s fight against the huge group of thugs near the end of the episode another good opportunity. Robin’s five Quickfire moves are:
Tap LT (L1): Shuriken
LT + X (L1 + Square): Explosive Gel (again to detonate)
LT + Y (L1 + Triangle): Zip Kick
LT + B (L1 + O): Snap Flash (again to detonate)
Double-tap RT (R2): Bullet Shield Bash
Shield Bash 5 different thugs
As Robin, quickly press the right trigger twice to perform a Shield Bash. Use this move at least once on any five different thugs throughout the DLC episode to unlock this achievement.
Defuse all bombs in 3 minutes or less
Once you defuse the first bomb and Batman does his scan (this happens during the second time you control him), a five-minute timer displays on the screen. At that point, you have three minutes to get to the remaining two bombs. You must defuse the last bomb before the clock drops below the two-minute mark. Thugs and pathfinding will be your biggest challenges, so learn the route by watching the video and take down thugs as quickly as possible. Note that you do not have to deal with the sniper at all (even though we did), and can completely avoid him to save a lot of time.
As of the time of writing this guide, if you let the clock drop too low, or just feel like a fight is dragging on too long, you can exploit this achievement by reloading the last checkpoint. This actually adds time to the clock - more than you’ll likely need. However, given the probability that this will be patched, we’re showing you how to do it the honest way. You know, with our guide...
Breaking and Entering
Find a way into the secret base
This is a story-related achievement. You unlock it after interrogating the three thugs (as Batman) and using their codes to hack the door leading into Harley’s secret lair.
Zip Kick 5 different thugs
As Robin, quickly hold left trigger and press Y/Triangle to use your Quickfire the Zip Kick. Use this move at least once on any five different thugs throughout the DLC episode to unlock this achievement.
