defintely exists. too many conveyor belts with color coded boxes, that puzzle was kinda lame. It is cool that they made one more 8-bit metal gear game, since this plays a lot more like the MSX games than anything else. Has its own unique plot which despite being non-canon is pretty fun to experience. If you liked the 8-bit metal gears on the MSX then deffo check this one out, otherwise its pretty optional. Still cool that it exists though!
