Tempest Score required to get <10,000 Rank

Between 75K-80K right now would get you top 10,000. The value will probably go north of 80K though. So if you are close to that, then keep grinding. If not, I’d recommend getting your rewards and getting out while you can.

I'm at about 155,570 right now, and I'm at about 611 in the rankings, in case you were also curious about the score needed for the top prize.
