This certainly is great news. The Homeworld Remastered Edition is amazing and it is released.
You may buy it here Store.steampowered.com
From my experience, here is what i can say about it.
Its like the original Homeworld 1, but upgraded light years ahead, and it gives the same, epic feel in the single player missions like it did 15 years ago.
My childhood game, remastered. This is amazing i tell you.
As for modding the game, and the classic ones, is currently not possible from my end.
The mods that was made back in the old days doesnt work on the patched classic version of Homeworld 1 (Atleast not now), but only time will tell.
That be all folks.
Amazing that they made the remastered but its very buggy
Give it some time. They will patch it :)
