The phrase refers to the fourth main installment of a popular action-adventure video game franchise, specifically when considered for mobile operating systems. It implies the availability, or potential availability, of a high-definition console or PC game on smartphones and tablets. An example would be a hypothetical port of a title originally released for PlayStation 3 and Xbox 360, adapted to run on the Android platform.
Such a release represents a significant stride in mobile gaming technology, allowing players access to complex and graphically demanding gaming experiences on portable devices. This accessibility expands the potential audience for the title, moving it beyond dedicated gaming consoles. Furthermore, it underscores advancements in mobile processing power, making sophisticated gameplay possible on a wider range of devices.
