Okay, here is how to install Gizmo's mapo.
Download the "
client.zip" and "
server.zip" from
here.
Then place them into the folder:
Program Files/EA GAMES/Battlefield2/Mods/BF2/Levels/Operation_Firing_Squad
(You will have to create the folder Operation_Firing_Squad in the Levels directory).
Then extract "
Info" from the "
client.zip "and place it into:
(you should be able to just drag it out)
Program Files/EA GAMES/Battlefield2/Mods/BF2/Levels/Operation_Firing_Squad
And it should look like this...
Hope that clears it up for everyone
