F.A.Q.
Q: Is this the same as Hater%?
A: No, it isn't. The main difference is that for the ultimate challenge there is no retries and the whole run has to be to be done hitless (affects run and gun levels). Also the three parries on run and gun levels.

Q: Has anyone finish The Ultimate Challenge?
A: No, at the moment only TMR is crazy enough to even try it. But you are welcome to try it out.
