Boomer Rang'r - Genesis

Released by Data East in 1984, Genesis (internationally titled Boomer Rang'r) is an action game set in a prehistoric world. As a caveman, you must navigate an adventure to uncover hidden treasures on the island, using your boomerang as your primary weapon. A standout feature of the game is the ability to defeat the prehistoric creatures you encounter and ride them, allowing you to use their firepower in battle. With its expansive, mappable fields—a rarity for arcade games of that era—it is remembered today as a pioneer of the early exploration-style action genre.

Set in a prehistoric world, Warly, a caveman who uses a boomerang as his weapon, embarks on an adventure in search of lost treasures. Along the way, club-wielding cavemen, dinosaurs, and other prehistoric monsters stand in his path. Warly can also ride the dinosaurs he defeats, using them to breathe fire and battle his foes.
