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.

With the extraterrestrial mutagen now airborne, chaos broke loose in every corner of the globe: the monsters, long thought to be dead, now revived with even greater strength than before. An entire new generation of monsters rose by their side, and worse yet, a familiar evil began to stir again for vengeance. The second War of the Monsters had begun...
