There are no new Pursuits for the latest incarnation of the Midsummer Mutiny event in original flavor Defiance. You will be doing the same things in this event as you have one in prior years, and if you have already cleared all of those objectives, then you will ultimately be in the same place as always. This is not by accident; it’s specifically because the cutoff for Valor amounts for players is June 22nd, and any further Valor you earn won’t translate to more rewards in Defiance 2050. Since the Mutiny event runs until July 2nd, you can finish up any lingering objectives you’ve got early.
Of course, you don’t have to just wait for Defiance 2050, as the game’s open beta will run from June 22nd through the 25th ahead of the head start launch on July 6th. So you’ll have plenty of opportunities to do things, even if the event might not really feature into all of those plans. At least the reboot is near.
