The Multiplayer Beta for Homeworld Remastered is still being actively developed by the development team. As such, some issues may occur. We appreciate your patience as we work to make the Multiplayer for Homeworld Remastered the best experience it can be. If you have any questions or concerns, please submit a support request at https://support.gearboxsoftware.com.
In addition, the net code for Homeworld had to be re-written, as online services were originally powered by services that are no longer operational. This provided us with the opportunity to combine the maps, modes and ships of Homeworld 1 with those of Homeworld 2, along with some new modes and functionality from some of the modders we've been working with. As a result, in multiplayer, players will be able to choose between modes that encompass Homeworld 1, Homeworld 2, and Homeworld Remastered game types. One of the reasons we're calling multiplayer a "BETA" is because we want to work with the community to balance the game, so they understand this is something that we'll continue to update and iterate over time.
