I'm not certain. The meteor is almost here. We saw the cutscenes. Not don't there will be a final battle before shut down.

Hopefully thye have different leveled ones that all peopel can take part in. THose that got as far as Livign on a prayer can partake in the upper levels and get a closing cutscene.

Probably will be area battles in waves. OF group fights since there is a limit with the engines ability to display large amounts of characters on screen.
