Blessed by Newblood, this mod features all weapons from dusk, ported into Doom engine. The mod also features game achievements, game mutators and even an optional fork of ZMovement, called "Dusk movement" made by Ivory Duke himself.
So, the upcoming Doosk update will include dusk monsters. This monster pack will be part of the mod and can be selected through skill menu, that way you can toggle between doom and dusk monsters without quitting the game.
That being said, a standalone version of the monsters will also be released, as a separate download, for those who wants to play with dusk monsters, but without doosk.
Monsters will be mostly balanced towards vanilla health pools instead of dusk hp, so that way defeating the monsters will be kinda fair even with vanilla weapons.
Some monsters might have a larger hp, like the wendigo with 1/3 chan es to replace spectres, which have same hp as 2 spectres, so ammo management might become more important than ever.
And still no estimated release date for the update.
