Certain enemies, such as the baron of Hell, Hell knight, arachnotron and cyberdemon, have been made larger.New extra weapons (such as the submachine gun, railgun, grenade launcher, etc.) can be optionally enabled or disabled.
For example, the rocket launcher deals much more impact damage but has a lower rate of fire and a smaller blast radius, along with backblast damage that can be toggled off. All weapons have remastered and smoother sprites and animations.
