The trend of rappers having their own video games online is becoming more and more popular. While Juicy J's game caters to strippers and poppin' bands, Machine Gun Kelly's is all about punching nuns. Basically, you play as MGK and have nuns with knives going at you from both sides. It may not make sense but it's sure fun. Play it at the link below.
