Well, I just read through most of the threads, and it seems that not a lot of editing is possible because there are no tools (yet.)
But: I was wondering if it's possible to, like, fix a certian playable character so they are invincible, do more damage, etc. I know it sounds stupid, but I'm really really stuck on the campaign. :uhoh:
You could change the mission.lvl, change the rifle man class into darth vader maybe?
