Spy Fiction is an action-adventure game where a terrorist organization gains control of biotech weaponry and plans to use it on the world's population. The players take control of two special agents, Bishop and Shiela, members of an elite group called SEA Phantom Strike, who are assigned to neutralize the terrorist threat.
The gameplay is similar to Metal Gear Solid , using stealth and hiding places to avoid enemies. It also features a 3D camera that works with an optical camouflage suit to let players assume enemy identities. Players can use high-tech gadgets such as rappelling kits, wall climbing devices, sticky cameras, and more.
Players can manipulate the cutscenes and the game has multiple endings depending on how well they performed in the game. The gameplay includes an alert system where the alert bar turns from green to yellow to red depending on whether enemies have seen or heard them.
