Complex is a free advanced game modification based on Relic Entertainment's Homeworld 2 game engine, free of any business directive, developed with passion and hard work, for experienced RTS players only.

In a world of simplified games often under pressure to do well commercially, our challenge has been to create this ambitious project, for those who want more from a modern videogame.
Complex series, actually counts more then 5.000.000 downloads and up to 3000 contacts per days.

Don't use desure, download the file from here. Complex doesn't need desura to be installed.

Also, should desura be updating to the latest version as my copy is running 7.1.4 instead of 9.1 that is being advertised

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

Not what I meant. Desura installs it fine and it runs complex, but only complex 7.1.4-Any thoughts why? Also, i'm running Windows XP NOT 7.
Edit: Have tried a manual download, will see how that works.
