Comparison of free software shooters
About a week ago, Joe Barr posted a feature on Linux.com titled “New Alien Arena 6.10 blows away its FPS competition” yet gave no real comparisons with other similar games, regretable since his conclusion was that it “blows away its competition”. This was done in the same style as Barr’s previous feature, “Tremulous: The best free software game ever?” which described Tremulous but also lacked comparisons and relations to other games. This feature hopes to be a thorough comparison of the major free software shooters.
There have been many free software first-person shooters (FPS) projects over the years, from modded Doom and Quake engines to enhance the existing games (ezQuake, EGL, ZDoom), to free art packs such as OpenQuartz or OpenArena. In 2002, along came Cube, a single and multiplayer FPS based on its own engine, including artwork, maps, models and an ingame map editor. In the freeware (and Linux compatible!) world a little-known game called Legends, a Tribes-inspired game, appeared yet remained closed-source. Filling the FPS gap in the open-source world has usually been left up to commercial companies who release their games with Linux support (i.e. Doom3, Unreal Tournament 2004, Loki Software’s work) or freeware games produced by commercial studios(i.e. America’s Army, Wolfenstein: Enemy Territory) or simply running Windows games run via wine. In the last few years a few built-from-scratch community-based FPS projects, most built on the GPLed Quake engines, have popped up, among them are Tremulous, Alien Arena, Nexuiz, and War§ow. Some have kept their art assets under a closed license (War§ow), while others have also released their art under an OSS license (Nexuiz), I consider both categories free software since well, software refers to programs, code and procedures, not artwork. For this comparison, we’ll take a look at active, robust and community-developed free software shooters.
