The Nerf Laser Ops Pro AlphaPoint blaster 2-pack gives players everything they need to face off in head-to-head live-action laser battles right out of the box!* They fire a single-shot IR burst with each trigger pull and register hits with lights and sounds, while lights on the back display health status and ammo capacity. The blasters have unlimited ammo and a quick-reload button to replenish supply. Select to face off in teams or in a free-for-all. Adjust for the environment with the indoor-outdoor switch. Battlers can amp up their play via the Nerf Laser Ops app by using the included armband† to wear a smartphone device (not included) on their arm. On the app, they can access real-time battle intel that allows them to customize the blaster, track their performance, earn power-ups, and use GPS to locate opponents during battle. Includes 2 blasters and 2 armbands. Not compatible with Nerf Lazer Tag blasters.
