Brutal Doom review. Classic Game Room presents a CGR Undertow review of Brutal Doom for PC developed by Sergeant Mak IV and published by Mod DB. Brutal Doom is a Doom mod released in 2012 that enhances Doom without sacrificing its tried and true format. This mod changes the weapon sprites and damage they do and also adds new animations to both the monsters and the player characters. The monsters have also been tweaked to be faster and more damaging. In order to play this game, one must have the PC version of Doom and a source port installed. There are many source ports to choose from, but the one used in this review was GZDoom. In order to play this multiplayer one must have the source port Zandronum installed.
