Another mission Idea

Civilian rescue from a Planet

Basically, there would be a timer, you would have to fight your way to designated outposts, (having several on the planet, some with civilians, some without) and each time the mission is done, the civilians would spawn at different random outposts, making the mission a new one almost every time. There could also be thinks you would have to activate to get in the posts, say, turn the power back on to open the gate, or an outpost thats been booby trapped that you have to walk through without touching them.

yeah, thats all I got so far.

I totally like this idea but theres only one problem with it. The map size is pretty much full of arenas and there isn't too much room left over. However these may be an alternative...

1) Have portals thats heroes can travel through, bringing them to other areas(Boss Arenas)
2) Have this take place at the Colossuem
