Guys, as the title suggests, does Freespace 2 have a skirmish mode where you can play with and against the AI? So far I'm only seeing the campaign. I have downloaded some mods for the game through Knossos (although I haven't tried playing them since I plan on finishing the vanilla game's campaign first), and judging by the gameplay videos of those mods I found on YouTube, it seems that they also only contain a campaign mode. Thanks!

One more thing! Does the game not have a mission selector? I'm referring to the feature where you can select the missions from the campaign individually so that you won't have to restart your progress just to replay a certain mission in the campaign.

EDIT: I might've found the solution to my own problem lol. Apparently there's this mission simulator that I can use to replay the campaign missions that I've played as well as single missions that are not part of the campaign (I have no idea what these missions are supposed to be). Moreover, three of these single missions, the gauntlet ones, work more or less the same way as how I expect a skirmish mode should be. So everything's fine then. I still appreciate those of you who've managed to read this post of mine, thanks!

Haha, glad you found 'em. I love the gauntlet missions -- I really wish more games had 'modes' like 'em. Just endless waves of progressively more difficult/numerous foes. They're especially fun in co-op.
