Retaliation Engine

The Retaliation engine is a video game engine designed to have good performance on lower-grade hardware, while still maintaining photorealism, moderate-to-high frame rates, and quick loading times.
The game engine was created by Prime Studios, a rising developing company, during the development of Retaliation: Fires of Combat. They were dissatisfied with the performances of multiple engines available, since the IW engine had been in use for almost a decade, and engines such as Frostbite and ForgeLight yielded less than par results on lower-grade hardware, one of the claimed selling points of Fires of Combat.
The Retaliation engine originally had no official name, and it was dubbed the 'Prime Engine', based on the name of its developer and original game. The engine was officially named the 'Retaliation Engine' in 2015, shortly before the release of its namesake, Retaliation: Fires of Combat.
After the release of Retaliation: Endgame, Prime Studios lost rights to the Retaliation series, including its proprietary engine, to DESI, when Prime Studios split from its publisher. Prime studios turned to IDI for it's Ultimate Experience Engine to be used in their next project, Meltdown. Shortly after the release and subsequent success of Meltdown, Prime Studios won a lawsuit against DESI, and they regained ownership of the 'Retaliation' title and engine. Using their experience with the UEE, they created a massively upgraded version of the engine, Retaliation 5.0, to be used in Retaliation: Sub-Zero. ''
