the monsters and weapons have been redesigned so that they look more like the ones in doom and doom 2. each weapon received new attachments, so they play differently than they did in doom (2016). the game also added new mechanics like extra lives, wall-climbing, air-dashing, swinging from monkey bars, and swinging from grappling hooks. the player also received a flamethrower so that they can gain armor points when they damage inflamed enemies. the game is designed where certain body parts of the demon enemies can be damaged, so attacking and destroying those body parts can disable certain attacks and make them easier to kill.
