It is a vanilla DOOM 2 styled map with a bit of atmosphere, some custom atmospheric BGM and a lot of secrets, including a hidden exit - though that exit doesn't lead anywhere special for now, this is just a single map. Id say its between Doom 2 and Plutonia in general difficulty, and takes between 30 minutes and 1 hour to complete.

Doom II: Hell on Earth is a first-person shooter developed by id Software and released in 1994 as a sequel to the original Doom. The game continues the story, with players battling through Earth after it has been invaded by demonic forces. Gameplay remains similar to its predecessor, featuring fast-paced combat, maze-like levels, and an array of weapons, including the introduction of the powerful Super Shotgun. Doom II also adds new enemy types, such as the Arch-vile and the Mancubus, increasing the game's challenge. Initially released for MS-DOS, Doom II has since been ported to numerous platforms, becoming a cornerstone of the FPS genre.
