BZFlag – 3D networked multi-player multi-platform tank battle game

BZFlag is a 3D multi-player multiplatform tank battle game which allows users to play against each other in a network environment.

There are five teams: red, green, blue, purple and rogue (rogue tanks are black). Destroying a player on another team scores a win, while being destroyed or destroying a teammate scores a loss. Rogues have no teammates (not even other rogues), so they cannot shoot teammates and they do not have a team score.

There are two main styles of play: capture-the-flag and free-for-all. In capture-the-flag, each team (except rogues) has a team base and each team with at least one player has a team flag. The object is to capture an enemy team’s flag by bringing it to your team’s base. This destroys every player on the captured team, subtracts one from that team’s score, and adds one to your team’s score. In free-for-all, there are no team flags or team bases. The object is simply to get as high a score as possible.

Features include:

  • Variety of game types including:
    • Capture the Flag -each of the four main teams can have one or more team flag and one or more team base, both colored to match their team. For each team, the objective is to capture enemy team flags by grabbing them and bringing them back to their own base. Each team also tries to prevent the enemy team from capturing their own flag..
    • Open Free For All – the objective is to shoot other tanks to earn points. Teams do not matter, and all tanks are allowed to shoot other tanks.
    • Free for All – the objective is to shoot enemy tanks to earn points. The four main teams should not shoot other members of their team as this will result in a penalty. Rogue players are allowed to shoot any tank, even other Rogues.
    • Rabbit Chase – a single Rabbit is chosen by the server. All of the other players will be Hunters. The Rabbit has the opportunity to score the most points, but it is also the most vulnerable. When the Rabbit is killed, a new Rabbit is selected by the server.
  • Three types of flags:
    • Team flags.
    • Bad flags.
    • Super flags.
  • Four main teams: Red, Green, Blue, and Purple. In the Free For All and Capture The Flag game modes, each of those teams work together to fight the other teams. Teammates should not shoot each other in those modes. In the Open Free For All game mode, the teams do not matter and it is allowed to shoot any tank for points.
  • Two methods of implementing artificial intelligence.
  • Large collection of user-generated world maps.
  • Translated into 12 languages besides English.
  • Implements UDP unicast relay networking for better timing and stability compared to TCP.
