Double Dragon 3: The Rosetta Stone (ダブルドラゴン3 ザ・ロゼッタストーン Daburu Doragon 3: Za Rozetta Sutōn?) is a side-scrolling beat 'em up produced by Technōs Japan that was originally released as an arcade game in 1990. It is the third arcade game in the Double Dragon series. The game was not internally developed by Technos, who were busy working on other projects at the time such as WWF Superstars and The Combatribes. Instead a company called East Technology, whose previous work was the 1989 arcade shoot-'em-up Gigandes, was contracted to develop the third game in the series, resulting in a sequel with a drastically different gameplay and graphic style than its predecessors. The game was controversial upon its release due to the addition of item shops where players acquire power-ups by inserting real money into the cabinet, which was removed from the later Japanese release after negative feedback from playtesters.[1]
