Play Nangoku Shirei!! - Spy Vs Spy (japan) Online

Nangoku Shirei!! Spy Vs Spy came out for the Nintendo Entertainment System in 1987, published by Kemco. It was part of that wave of games where developers were really figuring out how to make two people compete on the same screen, a common challenge on the NES.

You control one of the two classic spy characters, running through a multi-room island hideout. Your goal is to find five pieces of a secret document and then escape via the airport before your opponent does the same. The core of the game is setting traps in rooms, like bombs or spring-loaded boxing gloves, to slow the other player down while you search drawers and cabinets for the items. You move screen by screen, and the constant risk of running into a trap or the other spy creates a tense, frantic pace. It feels like a chaotic race where a single mistake can cost you the entire match.
