With the level 3000 powerful release, clearing Super Rush 3 has become much easier. It's quite a long time, so clear it when you have enough time to release RUSH4. Since it was intended to be released, the challenge was cleared fairly appropriately, so an S decision was made. The rank judgment of RUSH3 seems to be rather unfriendly.
The last BOSS also wins by mixing level 3000 alone. It's easy up to about 1th, so I don't have much trouble even at level 20. You will be able to complete it from 2000th or higher by mixing Level 20 per person in one battle. I made a list because the challenge confirmation is quite a pain. If you would like, please follow the link below.
I'm really tired from the 3 races of RUSH30, so I haven't challenged yet, but RUSH4 seems to have been able to afford all five races and time. It's a lot of fun to fight without energy and I'm grateful to the fans, but there are too many battles...
