There are four achievements/trophies that are tied into the games combat system and using the various takedowns, gadgets and combat maneuvers at your disposal in order to defeat enemies. These achievements/trophies include ‘Brutality 101’, which I consider the hardest in the game to complete but with a little practice and a lot of luck you should be able to unlock them all in time.
Here's a list of said achievements/trophies and how to accomplish each:
Description: Perform every type of predator takedown.
Collecting this achievement/trophy requires that you knock out an enemy using all 22 types of predator takedown. These takedowns refer to the takedowns undertaken whilst being stealthy. They include the following:
- Ceiling Takedown

- Drop Attack

- Environment Takedown

Perform every type of predator takedown.
Between melee attacks, counters, quick-fire gadgets and an array of contextual takedown moves there are a huge number of moves that are available for use during combat in Batman Arkham Knight. This achievement/trophy requires us to use 15 different attacks within a single combo and is by far the most difficult in the game to pull off due to having to:
- Maintaining attacks to keep the combo alive,
- Prevent taking damage to keep the combo going and
- Remembering to use a sufficient number of different moves.
- Keep an eye on your combo meter and use different special takedowns each time you are able to add to your differing attack counts.
Perform 15 different combat moves in one FreeFlow.
Cycle of Violence
Description: Use 100 Quick Gadgets while in free flow combat.
Just about every gadget in the game has a quick-fire mode that can be used during combat to keep combos ticking over, stunning enemies and giving you a bit of an edge. This achievement/trophy requires that you use these quick-fire gadgets a cumulative total of 100 times across the game. Depending on your plays-style, this should unlock somewhere towards the game, however if you are a little more conservative with your gadget usage, it can be achieved by simply spamming quick-fire attacks between melee attacks.
Quick-fire attacks are linked to the following gadgets:
- Explosive Gel
- Remote Electrical Charge
- Freeze Blast

Death and Glory
Description: Take out 20 thugs with fear takedowns.
You’ll be able to activate Fear Takedowns from quite early on in the game. To trigger them, you’ll firs need to complete a Silent Takedown on an enemy. When you do this, you’ll see a yellow Bat icon with ‘Fear’ written next to it. Approach an enemy undetected and hit the ‘Fear Takedown’ or ‘Fear Multi-Takedown’ when the button prompt appears to knock out said enemy. Repeat as many times as necessary to unlock the achievement/trophy.
