Quake Combat+ is a refinement & continuation of Quake, SMC & Quake 1.5, built on Darkplaces, aiming to provide the ultimate Quake singleplayer combat experience and perfect the existing works without straying far from the original design/balance to retain compatibility with the many great custom-made user maps out there.
It's back baby! Largely similar to the berserk pack in doom, with one major exception: it is only for the current life, even if you load game. Keep your finger off the quickload key and don't die to reap the rewards.
Berserk mode boosts Axe and Kick damage, knockback and flinch frequency
New feature not pictured: If you're not sure of your berserk status, toggle the flashlight. It will have a red hue if you are berserk.
