It's not in the official announcements yet, but it's up on Twitter.. and anyone that follows the in game calender already knows but..This weekend is an upgrade weekend.
You have until maintenance starts to stock up on any Phoenix Kits you need before the Upgrade bonus kicks in. Once maintenance starts, the Phoenix Boxes are gone.
Last chance to get your Phoenix Upgrades before the bonus kicks in.. get them now. Given that this is only the 2nd upgrade weekend we have had this year so far.. it's looking like these are going to be rare going forward.
Take advantage while you can. Good luck with your upgrades!!
Discovery is good, it's you that sucks.
