"Rooftops" Campaign Installation Guide TEXT

1) Copy all four folders (main, zone, mods, players)

2) Open your Call of Duty 4 game directory and paste them there. 
Overwrite the existing files (nothing is modified in the base game, so don't worry about making a separate
game folder)

3) Find your iw3sp.exe in your Call of Duty 4 game directory, make a new shortcut of that file in your
desktop, right click on that new shortcut and click properties. In the 
destination text, right after the game directory
(when the final " ends) put ONE space and then this line:
 +set fs_game mods/spi_rooftops_main
It should look something like this:
"C:\Program Files\Activision\Call of Duty 4\iw3sp.exe" +set fs_game mods/spi_rooftops_main
(Unless your game is installed somewhere else)
 
4) Launch the game from this shortcut

If you want to play the game without the Rooftops Campaign Mod, 
simply run the game without the shortcut you made.

STEAM USERS:

1) Right click CoD4 in your Steam Library and select Properties.
Click Set Launch Options and paste this line:
 +set fs_game mods/spi_rooftops_main
(Include the space before the command)

2) Run the game from Steam and it should work. 
If you want to play the game without the Rooftops Campaign Mod, 
just remove the line from Set Launch Options.

Spec-Ops Installation Guide TEXT

1) Copy the 4 items (main, mods, zone, sospi.cmd) that came with the Spec-Ops Mod download.

2) Go to your Call of Duty 4 game directory and paste them there. 
If you already have existing files, overwrite them. They are most likely 
previous versions of the Spec-Ops missions you might have downloaded in the past.

3) To run the mod properly, run sospi.cmd.
This will launch CoD4 Singleplayer with the mod enabled.
The .cmd file MUST be in CoD4 game directory to work properly.
(You can make a desktop shortcut of this file)
(If you have problem with the .cmd file and your antivirus check Troubleshooting below)

4) SPi implemented a mission select menu so you won't need to use the console to play the maps.
Once you run the game from the .cmd, the custom mission select menu will be available.

Troubleshooting:
If your antivirus sees sospi.cmd as a virus, exclude it. It's just a command line.
If your antivirus still doesn't allow the mod to run, you can do it yourself:
-Make a new .txt file.
-paste this in your .txt file: 
iw3sp.exe -start +set fs_game mods/sospi
-change the extension/format of the .txt file to .cmd
-go back to Step 3.

Steam Users: 
If you have the Steam version, the .cmd way of enabling the mod 
will unfortunately prevent you from using the steam overlay interface.
If you want to use it, you need to enable the mod from Set Launch Options by right clicking the game
and selecting Properties.
The command is:
 +set fs_game mods/sospi (make sure to include the space before the command)
