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.

In the year 1999, Umbral Hollows was a sleepy, isolated town, seemingly untouched by the passage of time. But beneath the surface, the town held dark secrets and horrors waiting to be unleashed. In the Hollows Haven Orphanage, a group of children lived under the care of the nuns, little knowing the terror that would soon plague their lives. In the present day of 2016, Umbral Hollows had changed little since that fateful night fifteen years ago. However, the town held onto its secrets, never revealing what had happened in the orphanage all those years ago. The town's people had tried to move on, but the memories of that night still haunted them.
