2 map packs that is for Homeworld 1 and Cataclysm.
This download included Map Packs for both Homeworld 1 and Homeworld Cataclysm, both in wich have a ton of maps to give you the playground for all your mods you have downloaded, or to simply duke it out against bots or players.
Just extract the Homeworld 1 ''Multiplayer'' folder into the Homeworld 1 game folder, and the one inside the hwc one into Cataclysm and run the game as normal and start a Skirmish.
I do not claim these maps as my own. I upload them here for achival purposes only.
