Unreal engine

Unreal Engine first came to light in the Unreal game, a first-person shooter published in 1998. Originally developed by Epic Games, it was made open source in 2005. The original version was released back in 1998 and 19 years later it continues being used for some of the biggest games. The strength of the Unreal Engine is its ability to be modified enough that games can be made into very unique experiences. However, this requires skilled developers with vast experience.
