enhanced clone of the classic first-person shooter Doom (server)

 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.
 .
 This package contains the server for network games of PrBoom+.
