Commission: Ryu and Ibuki vs 4-2

Here is a commission of Ryu Hayabusa and Ibuki teaming up to take care of Basilisk Mine 4-2 from the original Ninja Gaiden game on NES. Birds that do 3 ticks of health. Why do birds do 3 ticks of health? A bazooka only does 2. I bet Ibuki questions why all the wild life is out to kill Ryu.
