Unreal Engine (UE) is a 3D computer graphics game engine developed by Epic Games, first showcased in the 1998 first-person shooter video game Unreal. Initially developed for PC first-person shooters, it has since been used in a variety of genres of games and has been adopted by other industries, most notably the film and television industry. Unreal Engine is written in C++ and features a high degree of portability, supporting a wide range of desktop, mobile, console, and virtual reality platforms. The latest generation, Unreal Engine 5, was launched in April 2022. Its source code is available on GitHub, and commercial use is granted based on a royalty model, with Epic charging 5% of revenues over US $1 million, which is waived for games published on the Epic Games Store. Epic has incorporated features in the engine from acquired companies such as Quixel, which is seen as helped by Fortnite's revenue. In 2014, Unreal Engine was named the world's "most successful video game engine" by Guinness World Records.

A mysterious massive powerful evil force is sweeping across the corners of the Multiverse without any warning, laying many worlds in ruin. In these sieges, vast multitudes of heroes from many different alternate worlds were either killed or captured and brainwashed to do their enemies' bidding in a pursuit to remove any further resistance to the unknown growing threat entirely. This unholy persecution would be infamously known throughout the game as the “Genocide of Heroes”, a catalyst that would serve as a driving force to the events of the game. Only now aware of the growing number of ruined worlds and rapidly decreasing number of heroes in the Multiverse, the secret inter-dimensional combat organization Shinra once again acts and investigates matters that caused the Genocide of Heroes, the reason behinds the mass slaughters and the mysterious dark force that does everything horrific at this point behind the scenes. Eventually, as everything begins to unfold and the truth to unravel, all of the Multiverse is locked in a great war between good and evil that could possibly conclude the eternal strife between light and darkness and bring about the end of all reality as we know it.
