The devs were a little lazy when they made Red Hood's combat moveset and simply copy pasted animations from other characters. In any case, I think that considering that he has guns, he shouldn't bother much with kung fu and just shoot every criminal on sight. This mod makes that happens.

This mod is a simple command console code that replaces those copy pasted melee animations with his own gunshot animations, it also reduce the health of the enemies to %1 so they die with said gunshots immediately.

To install (in case you aren't familiar with the Arkham games command console mods):

1. Put the mod file (a.txt) inside this folder (for the Steam version, may work with Epic but I haven't tested it):

SteamLibrary\steamapps\common\Batman Arkham Knight\Binaries

2. Find your game's "BmInput.ini" file, found in this folder (again, for the Steam version):

SteamLibrary\steamapps\common\Batman Arkham Knight\BmGame\Config

3. Open "BmInput.ini" with a text editor (usually Windows Notepad)

4. Change this line:

Bindings=(Name="XboxTypeS_A",Command="DebugCamSingleFrameStep | EjectFromVehicle | BattleStrafe | ContextSensitive | Run | CapeGlide | AcceptConversation | Evade | DebugMenuSelectA | CancelBatarangCamera | TriggerPhysImpact")

for

Bindings=(Name="XboxTypeS_A",Command="DebugCamSingleFrameStep | EjectFromVehicle | BattleStrafe | ContextSensitive | Run | CapeGlide | AcceptConversation | Evade | DebugMenuSelectA | CancelBatarangCamera | TriggerPhysImpact | exec a.txt")

Now every time you press the "A" button in your Xbox controller (which is the sprint/parkour button in-game) the codes inside "exec a.txt" will be applied, which will apply the mod. If you prefer to use any other button or the keyboard, you can use Mr. Jag's method and bind the code to whatever key/button you want https://www.youtube.com/watch?v=fbVbkLzM8rY (is not hard to figure it out, but if you have questions, feel free to ask).

Note: remember that the gunshots are actually melee attacks, so you can't shoot enemies that are very far. That could be possible to fix (by increasing the range of melee attacks), but I haven't looked into that.

Credit to the entire Arkham modding community, I wouldn't have figured out any of this myself.
