Mod name: Calypso
Download and install: See the README to get the download link for the latest version. After downloading the pk3, Copy it so that the following file exists inside your openarena folder: Calypso/Calypso.pk3. Launch openarena, select Mods, and select Calypso, and enable some of the Calypso variables.
Calypso adds new features through variables controlled from the command console. These variables allow configuration of a number of weapon attributes, such as their: speed, air timeout, damage, reload time, bounce, and gravity. It optionally allows to make multiple projectiles be shot at the same time, with "spread" or "grid" fire. Other variables control when certain items spawn and whether you spawn with those items during deathmatch. It also contains the ultra-powerful "Clan Buster" weapon (a sort of rocket launcher causing explosions like Kamikaze powerup, that does not kill its owner; see video).
Note: the mod includes a feature that involves a potentially privacy-related issue: it does include a "whois" command available for all players, that although not actually showing classic "whois" (Domain/IP owner) infos, shows selected client's IP address (togheter with match-related player infos such as name, team, rank, score, deaths, impressives, excellents, etc). While playing Calypso mod online, be aware that other players get your IP informations quite easily.
Calypso also includes some features that allow server admin to write messages impersonating players and to positively or negatively interfere with their gameplay: its author defined this mod as "pretty evil".
Calypso last version is dated March 28, 2013 (based upon OA 0.8.8 gamecode).
After creating Calypso mod, its author moved on and created ChaosArena mod, that can somehow be considered Calypso successor and shares some features with it. ChaosArena name resembling previous "Chaos" mods in Quake/Unreal series is just a coincidence, it is not related with them in any way.
- ↑ Considering Quake Live weapons effect may theoretically further change in the future, it refers to values found in QL documentation during 2012/2013.
