Sorry for two help questions in such a short timespan, but when I set PlayIntro to 0 in base.rte/settings.ini, instead of skipping the intro and going straight to the main menu, it starts the Zombie Cave level!

Is there a way to fix this and make it go to the main menu?

Set PlayIntro back to 1, and press space to skip the intro.

I use this to launch a testing level right away, so to me it's a feature.

Levels are given an integer that assigns them a position in the campaign "InCampaignStage" or something.
If you set a level to 0, it goes there first.
Probably by raising that variable in the Zombie Cave definition you can make it not run that one.
Whether it will go to the menu I do not know.

Thanks for that advice, I will probably try that.

I don't like the intro because sometimes it refuses to skip, even though I press spacebar.

actually, you can do some cool things with that.

if you're in need to get into a quick game, a bit of copy pasting can make it so that it defaults to your favorite map in skirmish mode upon loading.

i belive the lines are in settings.ini and are called
defaultactivityname: zombie cave
defaultmap:blahblah

or something along those lines.

anyways, change the activity to skirmish ( i think) and the map to something awesome like grasslands
