Wouldn't that be Weapon Master Mode 200%?

If enough people want to run it then sure

The only issue with it being 200% is that weapons/costumes etc are only bought once. Not sure if that would make people lean to calling it 100% or not but just making the point

150% XP

Whatever it's called, I'd think this'd be a fun category. Definitely something I'd run.

If you can make up the rules and post them here then sure if people would run it.

So buying everything in all the shops wouldn't be required?

I think that should be required.

As do I, just wanted to point it out since it isn't stated in the potential rules above :P

200% seemed weird, but after playing around in Weapon Master I think what would be better is NG+. This is way harder than the first time and honestly even for me it's annoying.

I like the addition of survival 10, I'm actually probably going to do that next time I get around to these runs

I actually have an idea for it before people do runs so what I need to know is 5, 8 or 10 would be better. I say this because Team Battle has 5, Arcade has 8, and 10 is an arbitrary number.

Once that is established I would put that in the rules and then have the following sub categories Standard, Extra Standard, Death Match, and No Recovery. It doesn't seem standard has the Death Match and No Recovery options. Which is great because then there is no need to create a Survival Standard category.
