Putty Squad (lost Sega Genesis/MS-DOS ports; 1994)
Putty Squad is a 1994 video game sequel to Putty (1992). The game was developed by System 3 and published by Ocean Software. The player controls an amorphous blue blob, tasked with rescuing imprisoned putties. Putty Squad was originally developed on Amiga 1200, Sega Genesis/Mega Drive, MS-DOS, and Super Nintendo, but all of the versions, except for the SNES version, were cancelled for unknown reasons. All unreleased ports of the game exist.
The Sega Genesis/Mega Drive version was reportedly 100% completed in 1995 and reviewed in several European magazines. No evidence or trace has been left by the MS-DOS version.
The game was later remade for the PlayStation 4, PS VITA, and Nintendo 3DS in November of 2013. A month after, System 3 released the aforementioned Amiga port on their website. In October 6, 2015, A mostly finished Mega Drive prototype was leaked online but without Sound FX.
