This is the first update of the 9 series, and the decade for the Complex Mod.

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.

If you are on WiFi, that may be your issue. I used to use WiFi and it was VERY slow, but when I started using Ethernet, it downloaded in about 4 minutes.

I dont think the cheating AI is fixed, they seem to have another source of RUs because I made sure that the AI only has 1 mining operation yet they achieved the secondary objective of having over 40000 RU. How can that be?

You can generate RUs from your own fleet and cannibalize ships

Loving it so far, but then I realised.
If this is the last version, we are never going to see that incredibly beautiful User Interface that was shown a little while back.
That sucks. :(

I write from the translator... I long waited for the 9th complex, but something didn't understand. The uniform destroyer, something didn't see the such. Power plant and capsules, them unless it wasn't planned to move away? Well and still a question where it is possible to read the list of changes? And I while only change of the menu noticed that.

It's really stupid to assume that homeworld 3 will be anything like Homeworld 1 or 2, even if Gearbox Software says so. For all knows well, they may be developing the game to be a tactical simulation instead of an RTS game...

Homeworld 3 still may not be able to come to us for years, so i do not see why you need to stop modding the game because of the wait.

This is a lovely lovely piece of work.

However, I get very bizzare sensitivity change for viewpoint changes - only on this mod. Very confusing but the sensitivity is so high it makes this mode basically unusable without extreme mouse-sensitivity changes in the driver. Only on this mod though.

Windows 7 said it installed incorrectly, so tried running before Windows reinstalled it and afterwards, but the Desktop Icon only starts the vanilla HW2.

Target properties match the .big file in

C:\Program Files\Sierra\Homeworld2\Data

Target properties are

"C:\ Program Files\ Sierra\ Homeworld2\ Bin\ Release\ Homeworld2.exe" -mod Complex91.big -hardwarecursor -overridebigfile"

Tried removing 'overridebigfile' but nothing. Removed the other mod files, didn't change the screen resolution when prompted.

Any help would be appreciated team!

Ignore that. Apparently the game is installing it to the wrong place. If anyone else has this issue, you need to ensure the Complex .big file is moved to the secondary data folder in

C:\Program Files\Sierra\Homeworld2\Bin\Release\data

On my pc the mod installed fine but the shortcut (not the windows link) came out with the wrong address.
I had to edit the shortcut a remove an extra "\" in between " Homeworld2.exe" -mod Complex91.big -hardwarecursor -overridebigfile"
and it came out "-mod\ Complex91.big -hardwarecursor -overridebigfile"

Oh and the guest saying the same thing is me... I forgot to sign in.. LOL

ok when i try to use HW2 updated to 1.1 on its own it runs fine, when i try to use complex, or the sister mod (complex simple) i doubleclick the shortcut, the hard-drive starts up, and the mouse changes to a loading icon, but then does nothing, nothing opens.

I have watched the taskmanager in processes, and it starts but then just disappears.
