OpenArena is a PCFirst-Person Shooter for Windows, UNIX and Mac OS. The game is an open-source clone of Quake III: Arena, with the vanilla gameplay kept intact: score frags to win the game using a balanced set of weapons each designed for different situations. Like Id's game, the style of play is very fast and requires skill to be played successfully online.The gamemodes included are Deathmatch, Team Deathmatch, Tournament, Capture The Flag (all modes also in vanilla Q3), Harvester, One Flag CTF, Overload (these three from Q3's Expansion PackTeam Arena included in vanilla) Elimination, CTF Elimination, Last Man Standing, Double Domination and Domination (all of these additions)The game is compatible with many of the mods and maps done for Q3. Because OA is not finished, some of the many mods created for the original game couldn't be compatible.There's also a "missionpack" addon, which acts as the game's stand-on for Quake III: Team Arena.The game can be downloaded from its official site. Its current version is 0.8.8. and can be downloaded here.There are versions available for Android and Ouya, and the game itself can be downloaded via Desura.A reboot, called "Open Arena 3" is being developed, with a release date to be announced.
OpenArena has examples of:
Several tropes which apply to Quake III: Arena might apply here as well. Also, these tropes, unless noted otherwise, apply to 0.8.8.
The oa_dm* levels are the Quake 1 Deathmatch levels. These levels were GPL'd by Id for Quake's tenth anniversary. dm6ish (The Dark Zone) and ce1m7 (House of Cheethon) are also adaptations of dm6 and e1m7 from the original Quake.
The hydronex* (Hydrocapture) maps are loose adaptations of Unreal Tournament's CTF-Hydro16.
Thanatos Gambit: The player can set this one by getting killed (but not gibbed) and letting some seconds to pass, after which, the skulls explodes and everyone in it's radio area is killed, or at least, hurted enough to get killed.
Took A Level InManliness: Up to 0.7.7, Beret was a flamboyant boyscout. In 0.8.0 onwards, he was redesigned as a macho commando.
Use Item: The Teleporter, Medkit, Kamikaze and Invulnerability items.
Why Am I Ticking?: Hit an enemy with a Prox Mine, (or many, for amplified effect) and in 10 seconds, more or less, there's a high chance that he will blow into pieces.
