Maps (.unr) should be unzipped to the TacticalOps\Maps folder.

Texture (.utx) files should be unzipped to the TacticalOps\Textures folder.

Music files (.umx) belong in the TacticalOps\Maps TacticalOps\Music folder.

Sound files (.uax) go in the TacticalOps\Sounds folder.

This is the map-pack needed to play the so-called -X- maps. (The names of these maps all begin with "-X-"...)
Despite what the ReadMe file says, all these maps are playable with 3.3.2 (free UT mod) version of the game.

INSTRUCTIONS: This should be very simple, but it's also easy to screw up if you don't pay attention to what you're doing!

When you extract these files, there will be two folders: a "System" folder and a "Tactical Ops" folder. It's important that you understand that you have a System folder in the root directory of your TacOps game, and another System folder inside your Tactical Ops sub-folder. Everything from this download that is in the "Tactical Ops" folder will go in the proper sub-folder of the "Tactical Ops" sub-folder inside your TacOps game. The stuff in the "System" folder from this download belongs in the REGULAR "System" folder in your TacOps game directory -- NOT the System folder that is a sub-folder of the "Tactical Ops" sub-folder!

I'll say it again, in another way: After unzipping the download you will find two folders from the download: a System and a Tactical Ops folder.
~ Step 1: take everything from the System folder and place it in your game's System folder.
~ Step 2: open the Tactical Ops folder from the download and find the Tactical Ops folder in your game directory. The contents of each folder within the Tactical Ops folder of the directory should go in the same-named sub-folder of your Tactical Ops folder within the game. For each folder simply select all the files, copy and paste them into the appropriate folder in your game with the same name.

If this still doesn't make sense, try the ReadMe file that came with the download. If all else fails, throw me an e-mail and I'll try to help you out. (See below for contact information.)

New and improved weapons sounds! EXCELLENT soundpack!

Extract contents to the TO/TacticalOps/System folder -- NOT the normal TO/System folder, but the one inside the folder named "TacticalOps" in your TacOps directory. Then run the soundpack.exe to activate your new weapons sounds. You WON'T regret it! ...But if you're afraid you might, just be sure to make a backup copy of your TODatas.u file (copy it somewhere else - somwhere you could find it later) before running the soundpack.exe and before copying the new sound files into your TO/TacticalOps/System folder.
