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.

The description says supported platforms include Windows, Mac, Linux. I'm not finding a Mac version of this. Any pointers to where I can find that?

I click through the main site and hit a PayPal page in Italian. Do I have to donate to download the Mac version?

Thanks in advance for any help!

Great mod. Love it play it everyday when I have some time, though i haven't seen any updates concerning Complex 9, Is that still a thing or you are guys focusing on incremental updates (8.4.2->8.4.3->8.4.5 etc) ?
Really curious about what could come next :) .

Keep up that awesome work.

guys i have little problem - my ships does not autoattack unless they are attacked or i gave them orders personally... even if they are set to aggresive. Sometimes when battle was ending and there was only 2-3 enemy frigates my ships just stop shooting and waiting. Is there any solution to that?

Stupid and useless. It isn't anything like Homeworld.
