Robocop never officially hit the Sega Master System, and many wish it had never hit the Nintendo Entertainment System but that is another article altogether. The lack of a license has not stopped Korean based developer SIECO Ltd from creating a version for the Sega Master System. This version has recently been found and released by an online preservation website.
Okay, you already know that this game is going to probably suck since it is not licensed, true of the NES version too though, but because SIECO is not known for thoroughly playtesting titles. This is true particularly of unlicensed games that are simply being produced to capitalize on the popularity of the, expensive, license in question.
We have not played this version of Robocop yet but so far, online consensus is that it sucks. Download at your own peril.
