Gameoverse AU idea
We all know the story. Two game characters join an organization known as Facade to save the various game worlds by allowing the villain to win and the hero to lose to prevent their worlds being annihilated by Syntax.
But what if there was more than two factions?
As soon as game characters started hearing about this info from a mysterious informant, they'd soons set up their factions and made their intent clear to both Facade and Syntax. They're not interested in aligning with them and will protect their world if they every try to step their foot onto their worlds.
Adding more fuel to the fire, humans have a found a way to enter the Gameoverse without using a character leading to many to either forming their own factions or joining with any other already-existing faction. Then there are the abnormalities, they tend to vary in appearance that range from being glitch-like to being a fleshy abomination and only bring out nothing but death and chaos to the worlds, but they all share the same origin: They were intended to be weapons of destruction by Syntax but rebelled in one way or another.
This was going to be a long day for both Facade and Syntax.
