Oct 22, 2019 Doom II is Id Software's follow-up to their award winning Doom. Published by GT Interactive, it was released for DOS in 1994, just one year after its predecessor. Unlike most sequels, this one is actually good.

Version 2.5.0 released.

While you can still enjoy the original Doom and its progeny today in an emulator, modern games are held to higher standards of visual fidelity, usability, and multiplayer features. Doomsday Engine exists to refresh the technology of these classic games while retaining the core gameplay experience.
The Mac version of Doom 3 includes an additional data file named game02.pk4. If the PC installation of Doom 3 does not have this data file, then a Mac user cannot join a Pure Server game hosted by the PC. A future patch to the Win32 and Linux version of Doom 3 will include this data file.

After almost two years since the last release, the PrBoom Team is proud to announce PrBoom 2.5.0.
