This paper introduces the implementation of client and server for the FPS game which adopts the control element of the racing genre. Game playability is enhanced by combining the users interaction, shooting elements of FPS and the car control element of racing game. User’s tank can move along the slope and the client can stably synchronize with server independently of hardware. By deploying the neutral monster, game excitement is raised. Game server is designed using the IOCP socket to provide the multiplayer game. The proposed game is implemented, and shows the effectiveness of the combining method.
