However, please note that this source port is in Alpha stage right now, but it's currently being worked on.

It also only currently supports Catacombs Abyss, so if you want to play all three Catacombs, still use the Reflection Keen source port (https://github.com/NY00123/refkeen/releases) instead.

CatacombGL version 0.4.0 was just released, supporting all four Catacomb 3D games.

Main features:
* 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.
* 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).

This is very amazing. Best port available for this classic fps series. <3

Thank you! :)

CatacombGL 0.4.1 Beta has been released some days ago adding some very welcome things like an option for auto fire. Makes the whole experience much more enjoyable and less painful. Awesome.

As development continues, now CatacombGL 0.4.2 Beta is released. This release fixes various bugs and adds the fizzle fade effect to the level transitions and magic gates.

thank you!!!

Thank you for the encouraging feedback; I'm glad you like CatacombGL.

I'm currently preparing a new update, which will include some additional features that were suggested by various other players. I hope to have it released somewhere in December.

Any ETA on when this next version will be made available?

My plan is to release it in the week before Christmas.

The new version is out now: CatacombGL 0.5.0.

New in this release is an automap and an option to render in 320x200 pixels.

Thanks a lot for this early christmas present. :)

Thank you!!! I wish i saw it earlier. This is awesome and makes much more fun. In Catacomb Descent i was in the end of the game and i made the mistake to walk through the labyrinth and i came never out of there. :-)

You're welcome!
The labyrinth in Nemesis's Lair is indeed rather big and challenging compared to most of the other levels. Theoretically it's possible to win the game without ever encountering Nemesis, via a long alternative route through the labyrinth. But in practice it is easier to just head straight for the boss.

Just found this thread because I somehow miss it every time I view this forum.

Thanks for this!
