There's a very, very and very short new i have here regarding about Orange Madness 5 which is about its plot:

The plot of Orange Madness 5 will be a continuation from the plot of Orange Madness 4. In which, the main orange guy has indeed survived the headshot thanks to his "boss" and he indeed got a bandage on his head now. But his contract of eliminate sheriff under his boss's orders has been abandoned and terminated by the main guy himself for unknown reasons. However, he still works for his boss and his boss decided to give him a new contract that's gonna worth it. The main guy accepted to do that contract.

Guess, how the main guy's new contract mission will be like? Guess, we'll see :)
