A portly projectile indeed.
It looks like under enough force/drag some of the back mounted mechanism might spread into a gliding mechanism, which is really interesting.
Also those awesome Bowie knifes seem to be jet powered, which for mid air combat, or sabotage of Balloon based air travel, like zeplins.
final note, I really like the Mr Robot-pig logo, and glowing eyes are a nice tony stark type of touch.
Thank you for making this.
