Rocket Arena (RA) is a free modification (mod) for the multiplayer first-person shooter games Quake, Quake II, Quake III Arena and Quake 4. There are also ports for Half-Life (called Lambda Arena) and Unreal Tournament. Rocket Arena was created by David "crt" Wright of GameSpy and first released for Quake in 1997, less than a year after Quake'''s debut. It became a successful and influential user-created game modification. Gameplay Rocket Arena is very similar to standard deathmatch, in that players battle against each other for survival. The major differences are that the players all start with identical resources — weapons, ammunition, health, and armor — and that all resources are removed from the map, thus preventing players from improving their condition. These two conditions focus the gameplay towards fighting and away from more traditional deathmatch techniques that involve resource domination. Each Rocket Arena game contains one or more rounds. Each round begins by spawning players randomly throughout the map, or arena. Once a player is "fragged" (destroyed), he or she is removed from play, and allowed to spectate. When one team has no more players in the arena, the other team wins the round and the next round begins. The team that wins the most rounds, wins the game. Games are played continuously. Standard Rocket Arena mode Every player creates a team or joins a team depending on the set number of players allowed per team. A queue is formed and the first two teams play a game (which may include several rounds). The winning team stays at the top of the queue and fights the next team, while the losing team is placed at the end of the queue. Clan Arena mode Every player joins either the Red team or the Blue team, and these two teams play games continuously. Every player gets to play every round, and since there are no other teams, there is no waiting in a queue to play. Clan Arena became popular because players start off with all their weapons and are not able to hurt themselves or their team. Red Rover mode Every player joins either the Red team or the Blue team, and these two teams play one match continuously. In this mode, when a player is fragged, they immediately respawn as a member of the opposing team. This allows for continuous play, instead of having to wait for the next round.
