Mr. Tuff is a 2D platform game in development by Sales Curve Interactive (SCI) and presumably set to be published by Ocean in 1994-1995. The game was done by the same people as Super SWIV, and as such, the graphics are incredibly polished. The game was apparently too ambitious, and was never fully complete (although the game engine and graphics certainly indicate that it is close). The game follows a demolition robot known as Mr. Tuff. After the entire population of earth escapes to the planet Utopia, the army robots take over the world. It is up to Mr. Tuff to save the world for the peaceful domestic robots. The levels involve standard platform action, though there are a few shooter-esce hoverboard levels. Each world is set up into standard levels and a boss level.

In development by Bits Studios, RiQa was shown at E3 1999 and appeared to be heavily inspired by PlayStation title, Tomb Raider. It was a third-person perspective action and exploration game starring a female protagonist. The game was only shown once, and then was delayed several times before being dropped, with very few details provided. However, it is believed that Bits Studios later used elements from RiQa in its multiformat 2003 title Rogue Ops. Some prototype builds were dumped and released onto the internet on April 2024.

Double Dragon: The Revenge of Billy Lee is a beat 'em up game developed and published by Virgin Interactive in 1993 for Sega's Game Gear handheld console. It is a unique entry in the series, exclusive to the console, and implements many elements not seen in most other installments of the franchise. The game was entirely developed by Virgin Interactive, with no involvement from Technōs other than its licensing; as such, it implements many aspects not seen in most other installments of the Double Dragon franchise, such as the ability to use firearms. Furthermore, in contrast to the gameplay style and aesthetics already established by previous games, the Game Gear version takes a unique approach that is more similar to other beat 'em ups, such as the Streets of Rage series.

Sequel to the 3DS action game.
