I didn't make it!
i've installed the mode but i don't know how to use it to play with a Lan network.PLeas, tell me how to use it, i've tried everything!!!!!!1
I think coop_3.0 is a program that was used before the EA/Dice officially introduced coop into BF2. Thus, I believe the program is outdated, though I could be wrong.
You should be able to just boot up a Coop game in the mp options, and go to town. In order to get the larger sized maps you should download Andy's sp mod. He's got ones for both BF2 and BF2142 that put all the 64 player sized bot enabled maps into a single package.
FFOLKES unlocks mod is also great for using in sp/coop games. He has versions for BF2 and BF2142 as well. That mod allows you to play with the unlocks enabled, but there is no ranks and you can't use anything out of the mod towards ranked MP servers, only solo/coop non-ranked games.
