This is a project that originally stemmed from a file I named 'Doom Co-op' which started off way back in or with increased monster count more or less plus a few sound and minor graphics visuals but I eventually moved into actually adding new sections to both original sets of maps except episode 4 of Doom on top of making it suitable for single and co-op multiplayer. Standard and Hardcore editions are on the downloads list on the description. For the bloodthirsty and masochistic players, be it alone or with friends in co-op! MoC Overkill will throw more at you and will generally won't give you a breather for your trigger finger. Brutal Doom: Hell on Earth Starter Pack (Complete) file If you thought MoC Hardcore was tough, you haven't seen anything yet. Name changed to Maps of Chaos January 10th, Update to RC 1. Adds realistic gore, dismemberments, headshots, executions, lightning effects, particles, makes enemies smarter and harder, makes gun louder and beefier, and adds epic new boss battles. The definitive gameplay enhancement mod for the GZDoom and Zandronum engines.
