The Missile Launcher is a special accessory introduced to Hungry Shark Evolution in the 3.9 update on Mar 16, 2016. It has the ability to shoot prey with homing missiles, awarding double points in the process.
The Missile Launcher costs 900 gems to unlock. Alternatively, it can be unlocked for free by completing 75 missions. It can then be equipped by any shark in the 'Head Slot'.
When equipped, the Missile Launcher automatically fires homing missiles at prey. When hit, prey disappears whilst awarding double points.
