NBKFA

1: A cheat code for the game DUSK, published by NewBlood.

Typing said cheat code at any time while in game will give you all the keys, all the weapons, and max ammo.

It is assumed that NBKFA stands for: NewBlood, Keys, Full Arsenal/Ammo

Obviously a reference to IDKFA

1: "hey dude, if you're having trouble with a level in DUSK, try entering NBKFA!"

2: *in reply to some random tweet about people being dumb* "Ugh, NBKFA, right guys?"
