Just spotted something over at ZDoom that made my retro-heart bump: Doom Delta, a mod that DrPyspy is working on that combines the elements from the alpha, beta, and pre-release versions of Doom that he finds the most interesting. It is still a work in progress, but he has reached a point where he is comfortable showing off what he has done so far. The mod is spearheaded by himself, with some graphic design and all sound design being handled by a friend Stachekip. He plans for it to be compatible with any wad that was designed for Vanilla compatibility. Any map that takes advantage of ZDoom's TID system is not guaranteed to function properly. Some goals of the project are

• A functional alpha hud that includes a radar and instantly-updating readouts of important information, such as health, ammo, keys, secrets, and more
• Restored alpha/beta graphics for certain weapons and monsters, like the Shotgun and the Super Shotgun
• 3-4 'new' weapons inspired by the alpha/beta, including the Rifle and the Bayonette
• Scoring system inspired by ScoreDoom
• Restored lightning for the episode Inferno

Caught your attention? Then take a closer look at the ZDoom development forum thread.

Skillsaw, this crazy maniac did it again. Out of nowhere he released his latest megawad effort with the promising title Ancient Aliens. So what is it all about? Ancient Aliens is a megawad featuring 32 colorful, action-packed maps for Boom compatible ports and a soundtrack composed by stewboy. Next to skillsaw, some other mappers like mappers AD_79, esselfortium, Joshy, lupinx-kassman, Pinchy, stewboy, and Tarnsman joined the fun and left their mark on the project. So you can definitely expect the highest quality from the finest mappers around. Don't waste any more time and grab your copy of the second release candidate for your pleasure.

As rich as Doom's history is, we have to get back to lesser known times. No, not Wolfenstein 3D or Quake, but Catacomb 3D. The title, which would lead to a series of sequels, ascended from id Software's Hovertank 3D and, in 1991, offered the first semblance of what was going to the First Person Shooter as we know it today. Since 2018, developer Arno has been working on a port to modern systems. Instead of keeping things vanilla, this port targets accelerated systems. Entitled CatacombGL, the following features are available:

• Runs native on Windows 7/8/10. 
• Hardware accelerated 3D rendering via OpenGL, supporting widescreen resolutions, a customizable field of view and an uncapped frame rate. 
• Classic look is also supported.
• Player, projectile and monster movement with floating point precision.
• Configurable mouse and keyboard controls.
• Supports all four Catacomb 3D games as included in the Catacombs Pack from GOG.com.
• Supports The Catacomb Abyss version 1.13 (shareware).

There are, however, some limitations aswell as of the latest version (0.41 as of writing):

• No support for game controllers.
• No backwards compatibility with saved games from the original DOS game.
• No "demo" functionality (preview slideshow of Catacomb Armageddon and Apocalypse in shareware version).
• No fade-in effect when entering a level.  

To use CatacombGL, you need to provide the original files. So take your nostalgia goggles and set off for a trip down memory lane to ancient history, now revitalized for the modern computing environments of today.

Antaresian Reliquary is a compilation of levels, designed by antares031 for various community projects for the last 4 years. Seven levels with different themes and limitations were selected for this compilation, and the wad is designed as boom-compatible with some custom gameplay elements, such as new enemies and weapons. It is recommended to read the details about the gameplay changes, before you start playing this wad. Also, each level has a death exit, making every level starts with forced pistol start. So please keep in mind about this.
