Update: Umbra Deploy Challenge
A quick update on the Umbra Deploy Challenge to address some of your questions:
1) Only deploys (not upgrades) will count towards the 30M threshold.
2) The 30M threshold is NOT total unique deploys. It is cumulative deploys from all Agents during the event.
3) Upgrades and deploys count as the same action for the individual medal. If you deploy to slot 1 then upgrade slot 1, that will count as a single deploy for you. If someone else deploys to slot 1 then you upgrade slot 1, it count as deploy for both Agents.
