Honkai Star Rail isn't even out yet, but it's already clocked up a staggering 10 million users.
"10,000,000 Pre-registrations Reached!" tweeted developer miHoYo earlier today, reminding people to "pre-register now" to unlock rewards such as "Star Rail Pass ×20 and the 4-star character Serval (Erudition: Lightning) ×1".
