"Nangoku Shirei!! Spy vs. Spy" is an action-strategy game released by Kemco for the Nintendo Entertainment System (NES) in 1987. A sequel to the classic "Spy vs. Spy", it is set on a tropical island. Players must collect and assemble three missile parts before a volcano erupts, then escape via submarine. The game supports two-player versus mode, where players can set traps like mines, rope traps, quicksand, coconut bombs, and fire bombs to hinder opponents. It also adds elements such as shark attacks and sword fights for extra challenge. With a split-screen design, both players' actions are visible at the same time, boosting tension and strategic depth.
