The single-player mode takes you over a series of maps where you play against bots in a team.

Alien Arena offers plenty of configuration options. You can change resolution, graphical details, audio settings, run in windowed or fullscreen mode, configure mouse and keyboard.



All the configuration options can be set inside the autoexec.cfg config file, which should be located inside $HOME/.codered/arena. Once you enter your custom settings in this file, it will be automatically executed when Alien Arena starts. To execute it manually, open the console and type /exec autoexec.cfg. Take a look at $HOME/.codered/arena/config.cfg to see a list of variables, however, don’t edit this file.
