Dying Light 2 made some big changes to the formula established by the first entry in the story DLC, Bloody Ties.
Developer Techland says this is 'phase one' of the effect's implementation, and ask that players get out there, "smash some bones", and provide so that the developers can make it "iconic" for Dying Light 2 as well.
Dying Light 2 update 1.7.2 makes a bunch of changes and fixes beyond the addition of the X-ray effect. There are loads of fixes for crashes and stretched clothing and textures, as well as some significant gameplay tweaks. Nights are going to be much darker, and indicators for howlers should display correctly. You'll also find that virals' hearing has improved, and that they'll react more intensely to certain noises they pick up.
The full patch notes also include a laundry list of crash fixes, clipping corrections, and other bug smashing coming with this next big Dying Light 2 update.
