Heavy Fire: Shattered Spear is a first-person shooter game where you play as Will, a U.S. Army soldier tasked with capturing a spy who holds plans for a secret Iranian weapons facility. The mission is urgent, as failure to capture the spy could lead to nuclear war.
The gameplay is an on-rails experience, meaning your character doesn't need to be moved manually, but instead relies on the computer to move through the levels. Your main tasks are aiming, shooting, and reloading. After each mission, you can unlock new content from an armory using a skill tree with different paths. You can choose from various weapons, more ammo space, or abilities like faster reloading and extra health.
