That's awesome Forgo, thanks for sharing.
One thing to remind everyone when doing the OTIS Commander ... all vehicles should be picked up, they are not allowed to be used in combat, and if they aren't, then leaving them out is an obstruction for others.
I love being able to attend these assembled teams to take down the OTIS Commander for the crossover mission ... there have been a couple of them (maybe more) where at least two people got their Silver Crown in the same kill instance.
Gratz to Raindrop if this was his assembled team today.
