As had been previously announced to be in the works, an update has been released for the HDR and 4K support of Resogun on PlayStation 4 and PlayStation 4 Pro, as well as a few other tidbits.
Titled Update 1.10, the patch will provide High-Dynamic Range for the PlayStation 4 and 4K resolution (with confirmed supersampling) for the PlayStation 4 Pro, assuming you have a television that will allow for either.

The free update will also add some visual effects, lighting effects, and it will address some bugs that have persisted through the game’s 2013 launch on PS4.
Most recently, developer of Resogun Housemarque announced that its newest project will be a twin-stick shooter called Nex Machina.
