If upgrading to version 1.2, simply download and install just the "Mercs Onyx ReShade Release 1-2 Release.ini" file in you Anthem game folder and select the new .ini preset file from your ReShade menu once in game.

File and further updates will be moved to their own page soon. This a completely separate ReShade which tries to capture the essence of the E3 2017 Anthem footage while adding a grim aesthetic to the game. Video demo here: https://youtu.be/Rq_gK0pEU7Y
