VTG Sega Genesis 32X “Doom” Video Game 1994, Excellent Condition

My son recently found this game in a closet and it is in excellent condition! He loved this game back in the day as a teenager. Includes original box and cradle insert to hold game. UPC code was neatly cut from box, he must have mailed it in for something. As he no longer has his Sega, cannot test but he says it worked perfectly the last time he played it many years ago.
