Using the Nerf Elite 2.0 Double Punch blaster is super easy. First, insert 4 AA alkaline batteries into the blaster (batteries are not included). Then, load the 10 - dart clips onto the blaster. You can have both clips loaded at the same time. Once loaded, turn on the blaster and start blasting darts by pulling the trigger. The barrels will rapidly alternate, giving you a cool effect. When you're done playing, remove the batteries to save their power. It's important to wear eyewear while using the blaster (eyewear is not included) to protect your eyes. Store the blaster in a dry place to prevent damage. If the blaster gets dirty, you can use a dry cloth to wipe it clean. And make sure to keep the darts in a safe place so you don't lose them.
