Plotline The first step to creating any type of custom battle is to create a plotline. For this, you need a simple text program. Notepad...Wordpad...MS Word...those will all work. I, myself, am a fan of Notepad. Here is a basic outline of what you need to do for this step: Write out a historical background for your campaign. Whether it be based on a current competition that is going on, or if it's brand new, list some information giving whoever shall play your missions some sense of what is going on. Figure out what you want to happen in your campaign. From when the beginning of your first scenario is first started until the final minute of your final scenario, have it mapped out. It will make the actual creation process much easier. Divide your plan from step two into individual scenarios. Figure out what will occur in each scenario that is bringing it to a conclusion.
