Rival blasters (branded as RIVAL) fire small foam balls referred to by Nerf as "High Impact Rounds", but usually referred to as “Rival Balls” or "Rival Rounds" by the Nerf community. Nerf Rival blasters are targeted towards an older target market than Nerf's better-known dart blasters. Nitro In 2017, Hasbro released the Nerf Nitro line, which consists of blasters that fire foam cars into obstacles and stunt ramps. Ultra Released in September 2019, Nerf Ultra (branded as ULTRA) blasters fire a new, propriety dart design that is marketed as "THE FARTHEST FLYING DART EVER. Darts can travel up to 120 feet." The new Ultra darts are constructed from a lightweight foam that is notably different from traditional darts in that they are made with closed-cell, rather than open-cell foam. This construction allows for fins to be molded into the rear of the darts. Size-wise, Ultra darts are between N-Strike Elite darts and Mega darts in diameter, but shorter than both in length. They cannot be fired from any previous Nerf line or off-brand compatible blasters, nor can any other lines' darts be fired from Ultra blasters. This design was created in response to the growing number of third-party darts, including exact knockoffs from China, available for N-Strike Elite blasters at a much lower cost than Nerf-brand darts. Super Soaker Originally owned and marketed by Larami, Super Soaker is a popular line of water guns. Recently, Hasbro has released a line of Nerf-branded Super Soaker blasters. Lazer Tag Lazer Tag, a popular laser tag toy line from the mid-1980s, is also currently part of the Nerf banner. The current generation of Lazer Tag blasters attach to iPhones or iPod Touch units for enhanced playability. Nerf Dog In June 2013, Hasbro and Grammercy Products unveiled Nerf Dog, a line of Nerf-inspired canine retrieving toys made of rubber, nylon, and plastic. Nerf Dog was launched at Walmart stores, and debuted at pet specialty stores in Fall 2013. Based in Secaucus, N.J., Gramercy Products, Inc. is the manufacturer of Nerf Dog products. The Nerf Dog Tennis Ball Blaster mimics traditional Nerf blaster designs and shoots a ball up to 50 feet in the air. The toy uses special softer balls to reduce the risk of injury. Video games Nerf has also produced video game accessories for the PlayStation 2, Nintendo DSi, DS Lite, 3DS and the Wii. Visionary Media, Inc. released the first-person shooter
