Secrets & Spies

Secrets & Spies is a sub-series of Nerf Rebelle blasters that was released in fall of 2014.

Details
The Secrets & Spies sub-series revolves around a theme of sending secret messages via darts and "invisible ink". Most products released under the series come packaged with a special marker, designed to be hard to read on the series unique darts, Message Darts. The message is read by the use of a message decoder: a clear, red tube-like device which shows the message by canceling the red spots on the dart, which reveals the blue. Similarly, most products come packaged with a decoder accessory as well. Some blasters have red barrels or sections which show the message while the dart is loading in the blaster.

History
The Secrets & Spies sub-series was announced at the 2014 New York Toy Fair.

Code Red Collection
The Code Red Collection sub-series features re-released blasters with a new red and white color scheme. Like the Secrets and Spies sub-series, the Code Red Collection features hidden messages on darts and the blasters themselves that can be decoded with a transparent red message decoder.

Trivia

 * The concept of hidden messages was previously used with the Nerf N-Strike Elite video game and its Red Reveal accessory.
