This mod gives you the ability to build both races ships ie. If you play as the Hiigarans you can research and build Hiigaran ships but you can choose to research and build Vaygr ships and platforms,etc.. instead instead or a mixture of ships from both races. If you play as the Vaygr then you can not only research and build Vaygr ships but build and research Hiigarn ships,platforms,etc.. instead or a mixture of ships from both races.Also most of the Keeper and Progenitor ships can be build as well in multiplayer.
Hgr_Vgr corvette research descriptions,etc...updates
If I ever actually get into HW2 modding, it should be interesting to see how you separated the Hiig and Vay research.
It is not that difficult though.Just a lot of work to make sure you have the right research for the right Vaygr ship plus descriptions with the Hiigarans and vice versa plus making sure the AI knows which "new" ship is what type of ship,etc...
