frequency terror missions

[wolf619]

is it possible to change the frequency of terror missions to say once per month?

It is once per month... in vanilla.

Or are you asking about some mod?

is it once a month? I didn't realize that. Ok we'll here's what I actually had in mind, how would you set it so there are ONLY terror missions (no ufos) and they are about 2 weeks apart, that's what I'd really like to do. Thanks for your help by the way, I do appreciate it!
I was thinking about it but wasn't sure if it could be done, but I just played x-files so I know it is possible.
any idea on how to do this?

You have to set the mission delay timers. I assume you can eliminate other mission types by setting their timers to an absurdly high number. Retaliation missions must have their spawn chance set to 0%.

The frequency of terror missions is affected by shooting down terror mission craft. There is a delay added for shooting craft down and you can also edit this value. Change it to 0 to have the mission keep going at the same rate.

Only requires some edits to missionScripts.rul
