For anyone that hasn't already finished the meta objective for the Red Room event, I just wanted to point out that, similar to the Tachyon Anomaly event, the roster rewards for the meta objective are based on the lowest slot(s) of the hero you're using when you complete it.

For example, I completed it with my Kate, whose defense slot was her lowest. All 11 heroes got defense gear. After using my backup save, I also completed it with Cap, whose defense slot was his highest (the other 3 slots were all exactly 2 levels lower). As expected in that case, everything EXCEPT defense slots were rewarded.

So just something to keep in mind if you're trying to level or NOT level specific slots on a hero for any reason.
