Last stage in this sector. The last stage in a sector is marked red on the map. Also it always contains a boss that you must beat after your done rescuing refugees.
This time around it's a big ass cannon O_o It's nothing super hard bu taking out all those smaller cannons before fighting the big one can be tough. Otherwise just pound on it and try to dodge the falling shots which I failed to do miserably XD
