could you help me?
you go download "game_mod":
https://www.ugx-mods.com/forum/mod-releases/121/bo1-gamemod/10956/download the "game_mod.zip" , you will need a file reader like 7 zip or Winrar , you drag all the content of the file in your files of Black ops , there will be a "mods" file , you will download the map , unzip it (you take the file of the winrar one and drag it in the "mods" one) and you launch the game with "BO_mods" in the black ops files (i recommend you to make a shortcut of this at the desktop) and then you'll be in the game , go to mods launch the map , go to zombies and custom and enjoy :3
