Dinobreak is an action-adventure game that plunges players into a 1999-era metropolitan city under siege by dinosaurs. The game emulates classic survival horror mechanics, including restricted inventory management and infrequent save points. Players can switch between fixed, over-the-shoulder, and first-person camera perspectives during gameplay. A bonus arcade mode, "Operation: Feral Raptor," provides additional action.

The game embraces a retro aesthetic and tone, complete with intentionally stiff voice acting and extreme gore. Its core campaign is narrative-driven, tasking players with uncovering the origin of the dinosaur outbreak and finding a means of escape. Dinobreak also includes multiple difficulty settings, with new Assisted and Easy options available.
