Double Dragon 3: The Rosetta Stone

Double Dragon 3: The Rosetta Stone is a beat 'em up arcade game developed by Technos Japan and published by Taito in 1990.

Players can choose from four distinct characters: Billy Lee, Jimmy Lee, Marian, and Sonny. Each fighter possesses a unique set of normal attacks, special moves, and even distinct taunts. The game takes you across various international locations, from the United States to Egypt and Japan, as you confront a variety of enemy types. Combat mechanics include standard punches and kicks, as well as the ability to use special techniques that can deplete a character's health bar if used too often. A key feature introduced in Double Dragon 3: The Rosetta Stone is the addition of a shop system where players can spend in-game currency, collected from defeated enemies, to purchase new weapons, power-ups, and additional special moves for their chosen fighter.

The story follows the Lee brothers on a quest to recover the scattered pieces of the Rosetta Stone, an artifact crucial to stopping a shadowy global syndicate. You will encounter diverse opponents, including street thugs, ninjas, and supernatural foes. The gameplay progression in Double Dragon 3: The Rosetta Stone involves moving through linear stages, clearing out waves of enemies in each area before proceeding to the next. The addition of multiple playable characters and the ability to customize their fighting styles through purchased upgrades offers a different approach to the series' familiar combat formula.
