prboom-plus - 2:2.6um-1 main

PrBoom+ is an enhanced source port of the classic 3D first-person
shooter game Doom, first released by id Software in 1993. It uses
the Simple Direct Media layer (SDL) library and features an optional
OpenGL renderer. It is based on PrBoom, MBF and LxDoom, which in turn
are based on TeamTNT's Boom, a freely available port of Doom for DOS.
.
In addition to PrBoom's features, PrBoom+ offers uncapped framerate,
variable gamespeed, re-record, walkcam, chasecam, full mouselook,
FOV, and other features without loss of compatibility with the
original Doom.
.
PrBoom+ requires game data to run. Free game data is available in the
freedoom package. Commercial game data can be packaged using
game-data-packager. PrBoom+ supports all flavors of Doom, including
The Ultimate Doom, Doom 2 and Final Doom as well as Chex(R) Quest, HacX,
Freedoom: Phase 1 and Phase 2 and FreeDM.
