In any area where there's a hub with a grinder (Where you toss
Redmond in and pull the chain while he gets ground in the gears)
you can perform a very interesting glitch.

Start attacking the side of the grinder until Redmond goes into
Hyper mode. Then stand in place as Redmond keeps hitting the
grinder. You will notice that the Hyper bar stays up at maximum
and your combo chain number increases.

You can easily get a 1000+ hit combo in 3 minutes or so!
