No research center upgrade button, tried many matches with different version (including latest 12.2), waste.

Tested again, Research center upgrade option is unavailable in "Special Subsystem" section of mother ship. you cannot go beyond lvl Zero research center upgrade.

Suggestion:- There should be a way to bypass this option via other means for example (shift + right click -> drop box -> upgrade module)

Hey does anyone know how to activate the mod once downloaded?

Reply Good karma Bad karma+1 vote

Read the install instructions provided by the devs.

-remove all mods/addons in ...HomeworldRM\Data

-extract inside ...HomeworldRM\Data (both "Complex12.big" and the folder "locale" must be there)

-right click on your HomeworldRM shortcut in your desktop, add -mod Complex12.big at the command line (if you didn't create a shortcut, just create it by ...HomeworldRM\Bin\release\HomeworldRM.exe)

-it's recommended to play the english version, Complex is not localized
