Apr 28 (after maintenance)
New content update: [Unit Exchange] and [Armament Exchange] system
You can collect "Exchange Points" depending on the number of times you pull
from a spotlight portal. Then, you can use your Exchange Points to get a
Unit/Armament listed at an Exchange Lineup from the same spotlight portal
where you pulled from.
* The Units available from the Exchange Lineup will change depending on the
spotlight portal period, so make sure you check the schedule!
