I see. Yeah, I've also played a few missions for the last build, and at least Prison Escape or so was really good. I also tried making a really simple mission myself, with a map I created using the editor and then just the goal to kill every enemy. Alas, I utterly failed. Too bad.
Anyway, then at least I hope that there will still be more missions in the future, or possibly that making missions will at some point be easy even for people without programming skills.
Because, while I think that the myriad of custom weapons and actors, oftentimes with pretty cool new features, is very nice, I find that using them for typical sandbox games gets old after a while. I'd really just like a lot of varied missions, even if it's as simple as "Infiltrate that enemy base" or so
