Nearly nine goddamn years after the original Cacoward-winning mod emerged from the swamp of our psyche (and roughly half a decade after its last update), Reelism is back! The original development team has reassembled to completely rebuild the whole thing using the latest GZDoom functionality, allowing us to go above and beyond with bizarre and hilarious new features. If you never played the original Reelism, here's how it works: It's an arcade survival mode where gameplay is split into five sixty-second rounds. At the start of each round, three modifiers on a slot-machine style display are re-rolled, changing gameplay rules and what weapons and monsters spawn. Some of these are fairly normal, like, say, "explosive weapons" or "Imps and their many variants". Some are quite a bit less normal, like "drive an invulnerable tank", "swarms of the dogs from Wolfenstein 3D" or "shrink to the size of a Pinky's toe". If, after five of these rounds, you've somehow managed to stay alive, a strange and wacky boss will swing by to finish you off. Defeat the boss to achieve victory! Alternatively, die hilariously and vow to get a higher score next time!

The 'Master Levels for Doom II' is a grab-bag collection of various unstructured, unorganized WAD files, all made by various map authors with a wide variety of styles and design conventions. Most of the authors involved in the project, made these maps with the intention of them being a part of larger episode or campaign overarching a certain theme even before being contacted by id Software for this project of theirs. However, not all maps made by these authors were accepted by id Software, being later released freely by their creators after the fact, with some of them even continuing their work further, beyond the original submitted level sets. The Masterpack works by taking everything made by the authors past, present and future to the original Master Levels release and bringing it together in a single WAD file for your enjoyment. All 45 relevant (plus 1 bonus) map are now fully playable as 5 separate, organized episodes. And with this, you can now properly enjoy the works of Doom's early great authors, some of early Doom's most timeless work.

Nostalgia is a 32-level megawad for limit-removing source ports. It was released by Alex Decker (myolden) in August 2022 and combines vanilla-style aesthetics with modern map design philosophies. Most maps are smallish in size, with a focus on easy-to-medium difficulty and fewer than 100 monsters.

The midi soundtrack is assembled from various sources from inside and outside the Doom community, containing no bespoke tracks.
