B

==B - Info==
Okay, I'll get straight to the point. Still remaining classic to preserve it's legacy.
B is an unofficial sequel to A that has been deleted twice. Otherwise, the difficulty is a class 13 difficulty being harder than B is between Denial theoretically, but easier than Erratic. B was your FIRST Upper Gap difficulty, however thanks to the chart getting more classes this is no longer the case.
The obstacles in B are pretty tedious, if I do say so. Not only that, but it's the second in the letter chain. 1st we have the Soviet Union, so we can get it's enemy, NATO for B. Let's do it, sure. Anyways, this difficulty started out as a joke really, not much effort put into it. That was until TDE decided to snap his fingers and give this difficulty 1 week to modernize.
Give yourself a pat on the back if you somehow manage to beat this.
==B - Icon==
The icon is the flag, not logo of NATO (North Atlantic Treaty Organization) but cropped to a 1:1 since it's a difficulty, the icon is just coat of arms and navy blue background. Other than that, that's basically it. Since it's the opposite of A's icon, it makes sense for it to be like that.
==B - Obstacles==
Oh, B is so hard that we can't imagine a spectrum for it, so these are estimated.
===Obstacles===
* 2 million stud jumps
==B - Towers==
Let's be real. None of this exists, it's more of a trial. You can pick any part of B you want to complete, that is if you still exist, or you can do all, but you'll only be able to do none because of the sheer difficulty.
===Towers in this difficulty===

===Towers of this difficulty===

==Trivia==
*This is the 2nd difficulty in the Letter Chain, and technically what made the influence and idea of C and D.
**In turn, B was inspired from A.
*You don't need to censor the logo if you are using it in a video. But then again.. that's not unique.
*Lastly, B was originally made as a classic difficulty so it should retain like it,
*The icon of B is 1:1. or 360 by 360 pixels.

==Continuing from this point==
GG. I was gonna say for someone to continue C and end it after that, however due to reasons I will not say people kept going. Otherwise that doesn't matter anymore, just go to Erratic and let it carry you. Good game on beating half of the chart.
