A mappack is a random map script that contains multiple other random map scripts and generates a random one of them each time it is played. The contained map scripts can get chosen with equal or different probabilities, depending on how the mappack is designed.

When you generate a mappack using this generator, the selection part will be at the very top of the file. Once you added all maps you want, you can easily adapt the probability for each map before generating the mappack.

You can only use "plain" .rms files here, ZR@ maps will not work.
