F.E.A.R. Combat is a free multiplayer component from the original PC first-person shooter F.E.A.R., which lets you play against the owners of the retail version of F.E.A.R. as well as the other F.E.A.R. Combat users. F.E.A.R Combat requires a F.E.A.R. Combat authentication key that can be found at their main site.

  F.E.A.R. Combat works because it elevates first-person shooter combat to cinematic levels. And while we've certainly seen games with movie-quality combat before, you've never seen anything quite like this. Playing F.E.A.R. Combat is like battling through a John Woo movie like Face/Off, because when firefights happen in this game, they're downright glorious to behold. Bullets tear chunks out of concrete and wood; blinding clouds of dust and debris fill the air; bodies are torn apart or slump on the ground; and the deathly silence of the aftermath contrasts so sharply with the sheer chaos that erupted only moments before. Gunfights in F.E.A.R. Combat just feels right..
 

  OpenArena's game play is the exact same as Quake III Arena - score frags to win the game using a very balanced set of weapons each designed for different situations. Gameplay modes exist such as the popular deathmatch, Team Deathmatch, Tournament, and Capture The Flag (All modes also in the original game.) Since Version 0.6.0 you can play with bots.

OpenArena has undergone compatibility testing with some Quake 3 mods. A list of tested mods can be found here:

 Nexuiz focuses on bringing the FPS genre back to the basics with quick, lethal battles and balanced weaponry. As of the current release there are 9 weapons and 24 official maps, as well as 15 player models, with an average of 2 skins each.

 While Nexuiz is not intended to be an eye-candy laden game, it does however feature many advanced effects such as coronas, bloom, Realtime World and Dynamic Lighting and shadowing, shaders (with OpenGL 2.0), offset mapping, and High dynamic range rendering. All these effects can be turned off to make the game run on older hardware. Nexuiz has such a range of effects that enabling all of them would result in an unplayable experience, apart from on the most cutting-edge of hardware.

  Nexuiz is primarily multiplayer (though it includes a full single-player campaign, which allows one to play through the various multiplayer game types and maps with bots), and allows for hosting and joining of games. It can also support new game types, or whole conversions quickly applied to it (much like Quake). Nexuiz supports most, if not all, Quake modifications (although with varying functionality). Currently there are a few custom mods and maps used.

  Nexuiz development started as a Quake modification in the summer of 2001 by Lee Vermeulen. Soon afterward the project moved to the DarkPlaces Quake engine created by Forest "Lordhavoc" Hale, who later also joined the project. The original design called for a simple deathmatch project with a few levels and one character model to be released the next summer. After four years of development with no budget, Nexuiz 1.0 was released on May 31, 2005, completely under the GNU GPL, and by the end of June had over a quarter million downloads. Development continued after the initial release, with 1.1 released soon after, 1.5 released February 14, 2006, 2.0 released June 14, 2006 and 2.1 September 9, 2006.

  War§ow or Warsow, often abbreviated as W§W or WSW, is a multiplayer first-person shooter computer and video game first publicly released on June 8, 2005. The game is actively developed by a crew of freelance software developers and artists. War§ow prides itself on high-quality content standards with thorough testing by selected members of the community.  War§ow’s code base is open source software, distributed under the GPL; it is built upon Qfusion, an advanced modification of the Quake II engine. The artwork and other media is still copyrighted by its respective authors, although it is free to redistribute in its unmodified form.

  War§ow is based on the E-novel Chasseur de bots by Fabrice Demurger. The novel is the basis of the game's cyberpunk visual style, which is achieved by combining cel-shaded cartoon-like graphics with dark, flashy and dirty textures. Since visual clarity is important in maintaining competitive game play, War§ow tries to keep effects minimalist, clear and visible.

  While War§ow is still beta software, it has been accepted as a competition-worthy game by several large online leagues such as the Electronic Sports League and ClanBase. In addition to acceptance by large leagues, many specialized War§ow cups have emerged. Well-known examples are Bamboocha, a Europe-based War§ow Duel Tourney, and ESW : WARSOW, a Japanese War§ow cup. In 2007, several LAN tournaments featuring War§ow have emerged such as Crossfire Devotii Challenge 3, Warsow.nl LAN, and E-SPORTS STADIUM 2007.

  Additionally, War§ow has been featured on the German TV-channel GIGA Television several times, namely in GIGA eSports and its sub-shows Skill Sunday and Free For All and the Pay TV ITV station GIGA 2, also produced by Turtle Entertainment.


  The very competitive gameplay of War§ow focuses heavily on movement and trick jumping. Many of the tricks in War§ow originate from Quake series including circle-jumping, bunny hopping, strafe-jumping, double jumping, ramp-sliding, and rocket jumping. War§ow also gives players the ability to dash, dodge or wall jump, tricks that were originally possible in the Unreal series. The various movement tricks combine to add an extra dimension to the game play; as the player's proficiency at moving increases, they are able to collect health, armour and weapons more quickly, more effectively overpower enemies with their speed. The variety and flexibility of the physics has spawned an entire community dedicated to competing on the various Race maps that the game offers .

  War§ow also has a unique power-up system for weapons. In addition to regular ammunition, ammo boxes found on the map contain strong ammo. Strong ammunition either increases a weapon's power or modifies the behavior of the weapon to make it more useful and easier to wield. Weapons will use strong ammunition until the player runs out, at which point it will default to back to using regular ammunition.
