Join Mech as he leads our daily Star Fortress event which is a great way to group up to complete the daily and get some sweet rewards. There are 6 Star Fortress missions which are like short Flashpoints and they include a bit of randomisation to keep things interesting.
Loads of achievements in Fallen Empire->Star Fortresses
How To Join In Be online in Alpha or Beta with a level 60+ when Mech starts forming the groups at the event start time.
