A free and libre first person shooter
A long time ago, id Software released the source code for the Doom engine as free software. But only the program was released: the stuff for the game itself was still proprietary, meaning whatever corporation owned the rights could stop selling it forever, or pull it for being too politically inconvenient, or sully its memory by with an MCU's worth of "official" dreck, or anything else, and there'd be no (above-the-table) way for anyone to do anything about it.
A lot of people got together over the years to fill in the rest, so that you could have an entire Doom engine game available as free software.
They succeeded. In fact, they were so successful at getting more stuff to make the game there was a lot of stuff left over, and people couldn't agree on what should stay and what should go. So some people started taking advantage of that whole "free software" thing and made their own versions with what they wanted.
LibTech1 is one of these versions. Its name is a play on "libre" and "id Tech 1".
Differences from upstream Freedoom
- Non-GitHub repository using a "main" branch!
- Lightweight single-episode demo IWAD for running Doom on unusual machines!
- New E2M8 and Map30.
- Significantly overhauled E1M1, Map20 and Map29, among numerous other map tweaks.
- Restored old SKAG sprites, with some modifications.
- Minigunners use proper minigun sounds thanks to DeHacked.
- More easily distinguishable painbros.
- Key types that conceptually unify shape and colour.
- Rearranged music selections.
- New, more detailed lore, terminology and manual.
Download
All releases and source will be posted at the repository.
Sporadically updated pre-builds are also available:
Main build (11.9MB) last updated 2024-05-04

(Email me at verdantdregs at shaw dot ca to pester me to update this if the dates indicated are looking a bit too venerable.)
And, of course, you'll need a source port as well. Crispy Doom is a good start, or you can try Chocolate Doom for a more authentic oldschool experience.
