Time to start cracking some safes – Unreleased NES sequel to Spy vs Spy surfaces on eBay

Those looking to own a piece of NES-era history might want to click their way over to eBay.

A recent listing on the hugely popular online auction site has been posted offering an extremely rare Spy vs. Spy 2: The Island Caper prototype cartrdige for the Nintendo Entertainment System. While the title, which was developed by Kemco, did see a release in Japan for the Super Famicom in 1988, was thought to never have been developed for Western markets.

The opening bid for Spy vs. Spy 2: The Island Caper is a hefty $999.
