Talk:Credit Booster/@comment-72.188.64.104-20170814013833

If you got a 3 hour credit booster as your login reward, had got 3 day credit boosters on Sorties from two previous days, had bought a credit booster, it was a double credit weekend and it was your first mission of the day, and you did the Index High Risk (basically impossbile, I know)...

You could get 17,280,000 credits.

Although I'm not sure the first mission bonus works with the Index, but that's still 8,640,000 credits from one mission.
