Many additions to the game, new units, new features and better graphical aspect, but the more important improvements have been done on stability, gameplay and performance.
Every duplicate ship/subsystem have been removed, redundant functions cleaned, lagging scripts revisited, a lot of bugs fixed.

The game has been balanced to reach the better space battle experience.
I hope you enjoy all this work!

Full LOG here.

About the future of Complex, considering that Gearbox is working on the new Homeworld, this release is the last one for Homeworld 2, not the last one for Complex.
If the new engine will be great the new Complex will be on the way.

Thanks to everyone who's following Complex for so long time, Beghins.

I love this mod it's just awesomeness in downloadable form. Only 1 possible mod could beat this and that would be fusing Complex with the Pirates mod. Think of the possibilities.

I would recommend downloading the English version of the 1.1 patch here:


Install Homeworld 2 then install the patch BEFORE doing anything else.

Beyond that I can't help you.
