Type: Solo or group
Event: Occasionlly enough damage is done to a wall or floor section on a tileset during a mission to reveal an
opening to either an older part of the facility, an older facility that was forgotten about or an Ancient area
that had been sealed off long before. I am sure the timeframe and specifics can be made to suit many variations.
The first thing that would happen is you have a choice to go into the new opening or ignore it. It will stay
there for the duration of the mission until you exit or complete the objective with regard to the current mission.
The new tileset for purposes of risk VS. reward would take the combined total of your level and gear into factoring
what +1 to the difficulty over what you are equipped for. This difficulty factoring can of course be scaled to suit
many variations also.
Now my reasoning behind this is just to mix things up because you guys said you wanted "different" mission types
and i am sure this qualifies as different. Plus this would allow suprises that cannot be chosen ahead of time to
be placed in these missions or whatever fun you could come up with.
