It's called the Half Race Mod because originally in v1.0 there were no Cylons. In V2.0 we have Cylons, and they work as a race in their own right (complete with AI) so you can play against them (or as them if you want to nuke the colonies).
HRM is a bit different from most mods in that we don't have stations, all elements are mobile and if you're playing as the Colonials you probably want to stay mobile!
Other features of note, flak weapons, nukes, and an extensive list of ships.
This mod has been uploaded in two parts due to its size. Parts were split using 7-zip v9.2 and are compressed in rar format.
