One day, the craziest videogame idea I had ever thought of popped into my head during one of those "Don't do Drugs" presentations in high school. That should give you some context. It's called "Noble". And it makes no sense at all.
Reginald Noble awakes from his chambers and strolls around the military base. He is the only one dressed casually, and the only one in the entire complex speaking informally.
When war breaks out, Reggie breaks out his three-headed chaingun and charges out against the enemy forces in a brown/gray environment, with plenty of cover, and some extra second gun (like a shotgun, or something). It all seems like your average cookie-cutter shooter for a few minutes, until the freaky monsters start showing up.
Before you know it, you're fighting elephants with machine guns, pixelated things inside a 16-Bit dimension and battling flying textbooks that breathe fire and horrible flesh-hungry food in Mr. Noble's old high school.
It plays in a very oldschool style, reminiscent of Serious Sam, Duke Nukem or Quake. You've got weapons that shoot things like chickens and fireworks. Mines come in the form of wet cats, Reginald's melee attack is a headbutt and you gain health by chasing down anthropomorphic food that screams and runs away when it sees you (mostly doughnuts with eyeballs), all like the cheese or the key in Conker's Bad Fur Day.
Did I mention this game makes absolutely no sense and solely exists to be as ridiculous as possible?
