Call of Duty 4: Modern Warfare for the Nintendo DS is a specialized handheld FPS developed by n-Space. Unlike the console versions, it offers a unique campaign following the global war on terror in a fictional 2011 setting. Players switch between SAS and US Marine operatives to dismantle a radical coup in the Middle East and prevent nuclear disaster. The gameplay focuses on tactical shooting, utilizing the DS touch screen for precision aiming and mini-games like bomb defusal and hacking. With varied mission types—from boots-on-the-ground combat to gunship support—it delivers a high-action military experience optimized for the dual-screen system.
