This is an in-progress mappack for HWRM.
Most of these maps focus on unusual map elements, such as debris, radiation and pre-placed units, as well as more scattered and symmetric ru placement.
Simply copy and paste the Data folder over the Data folder found in C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM.
You can download or clone this repo, or just download the Data folder directly.
This will not erase any files except previous installs of this same mappack.
Other maps etc. will be untouched.
That's it!
