Event Map
You will have to operate within a special phase of Mirium space where Professor Cassada’s laboratory is located. This is an extremely hostile environment, teeming with Echo Tanks. Coordinate with your teammates and do whatever it takes to survive and return home!
sadly the mode itself will be forever overshadowed by the corruption WG put into the tiered loot boxes. And so the tale of mirny and mirium ends itself
anyone found out how to use the decryption keys?
There’s a big button that says decrypt. But you can only do that once you have beaten all the waves on all the levels.
It is hard. The best place to defend is the south west in the buildings.
The rewards are trash though even if you complete the event.
