Using this Miles Morales Tri - Shot NERF blaster is easy. First, take the 3 included NERF darts and load them into the blaster. Then, pull back the cocking mechanism. To fire, just press the button. But remember, you need to cock the blaster before firing each dart. When you're done playing, keep the blaster and darts in a dry place. Don't expose it to extreme heat or cold. If the blaster gets dirty, you can use a dry cloth to wipe it. Avoid using water or cleaning agents as they might damage the blaster. Also, always play in a safe area and make sure there are no people or breakable objects in the way of the darts.
