1. Can the Invader spawn new monsters in unexplored areas (ie: area 8 on 'Knee Deep in the Dead') while the marines are still in say, the start area?
2. Can the Invader activate monsters, which are part of the set-up in an unexplored area (ie: area 6 on 'Knee Deep in the Dead') and have them travel to other unexplored areas, such as area 8?
No to both.
