World Combat allows players to search for the enemy and work together as one unit to combat the enemy's force. Four players can play simultaneously as a platoon. Features a multiple function gun unit system that acts as a rifle, a machine gun, a scope and a rocket launcher. Players use the I/O assault rifle as their defensive weapon deploying various gun actions. The player can choose standard attack, machine gun or a scope to do the attack. The posture detection system will detect their posture with the gun and display a telescopic image to attack long distance enemies.
