Ex-rental copy, so it has that extra vintage vibe. Splatterhouse 2 is quite rare, and violent for an early 90's video game. Checking my photos you'll see a minuscule amount of damage to a small section on the upper left portion of the reverse side of the paper cover sleeve under the plastic. Plastic and rest of case are in good condition. 
Being ex-rental there is writing and metallic stickers on the cartridge, stickers on the paper sleeve, but overall the game is in great working condition. This game has been in my library, as all of my ebay offerings have been, for 25 years. Well stored and looked after. Tested recently and working great. It even has cheat codes on the inside of the case written in the 1990's!
