I bought the Homeworld remastered edition but I can't see how one unlocks Homeworld classic. I don't see any redeem codes and it is not present in my library.
Is it included in the Remaster's game files? Should I just download the whole thing?

I would appreciate any help.
Thank you.

Download the remastered.

When you install it, it gives you one icon. Open that and you get a screen with options for all four games.

There is also a way to go into the game folder after installation for a separate icon but I never really considered the default way a big pain, especially when I keep going back and forth to look at changes between original and remastered.

Once you have downloaded and installed the game just double clic the start file or start through Galaxy if you are using it and you get a launcher screen. Homeworld 1 & 2 remastered are at the top and bottom left of the launcher it says classics so just click the one you want

After installation has finished,it is possible to copy the whole two folders of the classic versions to Desktop.They are self contained games with their respective game data and executables located inside, and the remastered versions can be deleted which saves a lot of hdd space and the classic versions are better btw ;p.Cheers

Thank you to everyone who replied! I appreciate the help.
