Multiplayer quick mission?
 

Is there any way to play a multiplayer 'quick mission'?

(Or create a quick mission, then save it so it can be loaded in multiplayer?)

Some pals and I are trying to get to grips with the game, and don't really want to play the missions and give the details away before we know how to attempt them properly.

Well, if you know any map making, you can stick some enemy units in a map with very large random spawn areas so that it'll always be different each time you load the map.

Ah, I was hoping for something produced by the game (so we didn't know what to expect, and because I don't know enough about balancing missions yet).

That'll be a pretty good alternative though. I've done basic mission editing in some similar games, so I should be able to pick it up. Thanks for the suggestion.
