Prayers of Armageddon

Prayers of Armageddon is a Doom II megawad created by H3llraich. It includes 32 new maps and a hidden bonus map which is only accessible via using cheats. All the levels for the megawad were created entirely by H3llraich.

Originally H3llraich worked on Prayers of Armageddon in January 2009. The project froze just the next month due to major technical problems. The project was revived in January 2010 and released on September 24th, 2010. A bugfix version was released a month later.

Prayers of Armageddon requires use of a limit-removing source port. A ZDoom-based port is recommended for two reasons:
 * The wad does not come with a DeHackEd patch, instead opting to use the ZDoom-specific MAPINFO lump for custom map names.
 * Playing the wad in a non-ZDoom port may present bugs, e.g. making some secrets (such as the first secret in MAP01) unobtainable.

Prayers of Armageddon: Retaliation
H3llraich - more recently known as MFG38 - uploaded a video to his YouTube channel teasing a new Doom wad on May 28th, 2014. He later revealed that the video showcased a level from a remake of Prayers of Armageddon. The remake was titled Prayers of Armageddon: Retaliation, and it was created entirely by MFG38. A 4-map demo of the remake was released on July 3rd, 2014, followed by the release of the full megawad on December 5th.
