Run Boss Rush on high difficulty with 1 Life, without using high damage weapons. (My video)
As you can see, I didn’t pick up Neutron Gun which is my favorite weapon.
Neutron Gun has higher damage against all type of Space Crabs include CI5 version of it. (Same as Plasma)
It isn’t max difficulty, but props for 1 life and moron railgun! Too bad we can’t have V10.1 difficulty 
It’s not a max difficulty. The maximum difficulty is tier 16 + SSH
Did you like read my comment xD
And yes, I want the one that Military Chicken throws 7 grenades and 4 pairs of knives.
Nope xD
Or you can try Hardest Difficulty Yolk-StarTM with 1 live xD. I alway lose 1 live
I know that you have to play like noob, but did you know that if you stands over the U.C.O egg atomizers and then go upside down he will not hurt you?!
Lol, I watched with Dark Souls music playing in the background. It was epic!
For real, please stop. You have to stop necroing threads or he will unleash his wrath upon this forum.
I’m ready for it. What’s the worst that can happen?
The Stare of Doom.
