Open up TFW and select file ----> new tie battle. Then it opens a new battle*.lfd file for you then all you need to do is input all details.

Example:

General Tab: Add battle name and battle titles (usually only 1) and then put the system name at the bottom.

Missions Tab: here you will add the battle that will be used for the current run. in our case it would be like this. Select add ---> then find the mission file that will be used for the run and select it and it will auto add it. Then you can write a description if desired.

Battle map: you can skip unless you made a very small graphic here.

Galaxy map Tab: Here just use your mouse and move the red box around the galaxy to chose the place you wish the event to take place. This is what you will see when you first go and select the mission to fly along with the title.

Then all you need to do is save as: battle1.lfd and your done.
