The definitive gameplay enhancement mod for the GZDoom and Zandronum engines. 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.
Name changed to Maps of Chaos January 10th, 2015. "Full Package" includes the original and hardcore versions as well. If you thought MoC Hardcore was tough, you haven't seen anything yet. MoC Overkill will throw more at you and will generally won't give you a breather for your trigger finger, let alone using -fastmonsters/-fast. For the bloodthirsty and masochistic players, be it alone or with friends in co-op! Standard and Hardcore editions are on the downloads list on the description.
This is a project that originally stemmed from a file I named "Doom Co-op" which started off way back in 2006 or 2007 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.
The biggest difference between MoC Standard and MoC Hardcore is that I fixed up all the unclosed sector errors (courtesy of id that went unnoticed and were extremely minor) and some goof ups of my own (the E2M6 lowering floor HOM near start) when I jacked up the difficulty for Hardcore, on top of additional edits to two later Doom 2 levels.
On a side note, playing this with vanilla Doom or Doom 2 is not recommended as there are some linedefs that utilize Boom style line actions and at times more than 128 sprites visible in really hectic battles so if one must play "pure", use a limit removing port such as Boom/prBoom as the bare minimum.
Note: This is not Brutal Doom exclusive! You can play this with any mod you desire or even without mods!
Second note: This version is an official upload by the author and not by an unauthorized third party.
These are replacement levels only and is not an IWAD, so these cannot be used as an IWAD to circumvent the need for an IWAD to use PWADs.
