I explain the glitch halfway through the video so just watch it.

Go Act 2 Chapter 7

If you do it well you will easily get a 10x miltiplier and you pretty much have NO chance of going down because you are on the gas barge. Put it on insane and put on some hard mutators like no ammo pickups you will get 130,000 every time, and it takes LITERALLY 4 minutes if that

it removed the link to my video in my last comment.
Basically I found a pretty nice glitch to where you don't have to play the whole chapter and save yourself A LOT of time.
Oh, and I was getting about 600k points about every 5 minutes.

Just go on youtube and search "kacyraye"
That's my channel. I explain in detail exactly how the glitch works.
