I See Red Reshade

This Reshade preset renders the game in black and white, except for the color red. This preset affects everything, whereas the official black-and-white mode mainly leaves out blood and UI elements from the B&W filter.

Installation:

Simply place the I_See_Red.ini file in your game directory with Reshade installed. In-game, select the I_See_Red preset for it to take effect.

Note:

I recommend turning off lens flare in the setting, as it sometimes obscures your vision with another color. You may also tweak the color isolation effect to suit your taste.
