Long ago, a demonic attack sparked a war between humans and demonkind. Using power from the Supreme Goddess, the 68th in a line of heroes was finally able to defeat the Demon Lord and put an end to the conflict. The monsters lost their will to fight and transformed into women, and the great 500-year peace began.
One day, however, the femme-demons were once again overcome with a desire to rampage across the land. Suspecting the Demon Lord's resurrection, the Supreme Hoddess sent the hero Ernest to determine the cause of the great uproar.
When confronted by Nakara, Ernest is defeated and sealed into her dungeon. Now it's up to him and Victor, a mage and fellow captive, to find their way back home... And hopefully stop Nakara along the way!

I was originally going to write a cheeky description saying "We have Doom with Anime girls and coom at home" or something like that.... but the found out it is literally running on Gzdoom so the joke would have ended being to literal.... I guess you could also play it using the Gzdoom Linux build of the engine if you wanted too perhaps.
