I am having the exact same problem. Ive done everything that has been suggested. I think theres a miss communication here, at least for me. There was no zip it was an exe so everything was done for me. I found the warlords .big file in the data folder so im assuming thats what were looking for. In the gametype box in game, its only giving me deathmatch. This is starting to frustrate me lol. Im goin to bed. Edit: As a last minute thing i tryed this target "C:\Program Files\Sierra\Homeworld2\Bin\Release\Homeworld2.exe" -mod WARLORDSV0.29.Big -luatrace and vuala, i can select warlords.29 in gametype but then when i start, just homeworld ships...... ARGH, also the suggestion from the readme works, -mod warlordsV0.29.big now im really going to bed.
