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.

Welcome to the third installment in the First Person Shooters saga. Today, we will talk about two more solid choices for meeting people online - and then shooting them.

In the last article, we have reviewed three excellent First Person Shooters (FPS) - OpenArena, Sauerbraten and Nexuiz ............Today, we'll talk about games where you play as a human - against other humans. Our two candidates are AssaultCube and Urban Terror.

If like first-person shooters, you'll love Sauerbraten. This open source game might not have the visual finesse of other FPSes, but what it lacks in the graphics department, Sauerbraten more than makes up for with its various single and multiplayer modes, including an experimental role-playing game mode, and a unique WYSIWYG in-game map editor.

Quake Live is a First Person Shooter game, very similar to many other Quake-based variants, an extremely popular and successful franchise of games developed by id Software. In fact, many Linux First Person Shooters are based on a variety of game engines, released as open-source by the company.

One of the most epic free open-source first person shooters has just released it's latest version with over 3000 changes to both the code and the artwork. It's truly impressive how far the game has come and with these new changes, the sky is the limit! Nexuiz is a very community driven game that runs on Windows, OSX and Linux. Check it out!

While quality native Linux games are rather in short supply, those that do end up coming out of the professional game studios end up being first-person shooters. If though you have been trying to find a new non-FPS game that has native Linux support, there is a new one emerging and that is QuantZ.

AirRivals is a free-to-play massively multiplayer online role-playing game (MMORPG) with the characteristics of both Third-person shooters and flight simulators, developed by MasangSoft and owned by Yedang.

This post is a how-to, with screenshots, perfermance tweaks and links to the download and support.

Since the release of Nexuiz 1.0 in 2005, we have been tracking its progress as one of the leading open-source first person shooters. With time, this fast-pace game has picked up a nice level of artificial intelligence for its in-game bots, engine optimizations, single-player campaign missions, and a variety of technical advancements.
