 * Start with `onGameInit` to set up the most basic environment parameters, teams, hedgehogs, etc.

 * You probably almost always want to call `ShowMission` at the beginning of the game (`onGameStart`) to show the objectives of your mission.

 * Normally, the game ends when all hedgehogs are dead or one clan is remaining (unless `gfOneClanMode` is set). You can call `EndGame` to end the game manually.

The mission title and its description as shown in the mission menu must be edited in the missions files in `Data/Locale`. The file name is `missions_<language code>.txt`. There is one file per language. I.e. `missions_en.txt` for English, `missions_de.txt` for German, etc. Note that these files are supposed to contain the titles and descriptions of *all* missions on your computer. This makes these files unsuitable for sharing or inclusion into [HWPFormat HWP files], for example.
