In 2010 I released an E1 replacement for DOOM called Phobos Massacre. I was relatively inexperienced as a mapper at that time, and it really shows in the levels, which are quite bad.
I initially wanted to come back to this old mapset and just see if I could touch it up, but after looking over the levels I quickly realized that most of them were either unsalvagable, or they were in need of a LOT of work. So despite the fact that this mapset uses Phobos Massacre as a base, the content is about 75%-80% new. I've thoroughly changed each of these maps, scrapping sub-par areas and creating new layouts and architecture. In some cases, entire levels are completely new because there was no part of the old level worth keeping. Enemy and item placement has been reworked, co-op starts have been added, difficulty levels have been implemented, and proper playtesting has been done to ensure compatibility with -complevel 9.
This levelset is old-school, and as such you will break the levels or otherwise ruin the intended experience if you utilize jumping, crouching, or freelook.
I always balance my levels so that they play well from a pistol start. This often means that players who play these levels in succession will build up a large ammo stockpile, which some people gripe about. In my opinion, for the best challenge, you should try to play each level from a pistol start if you can. If you'd rather experience this as an episode, but still want more of a challenge, consider using the -fast command line parameter.
The music is mostly taken from The Plutonia Midi Pack which, according to its text file, may be used as a base for modification or re-use. The exceptions would be one track by Paul Corfiatis and one track by Graeme Norgate and Robin Beanland.
