The core gameplay loop centers on visceral, cover-based combat, requiring tactical movement between cover points to survive overwhelming enemy forces. A distinctive feature is the Lancer's chainsaw bayonet for brutal executions. The story escalates the conflict as the squad ventures deep underground to stop the Locust from sinking cities, uncovering the enemy's deeper motives.
