Joyride Studios/Halo 2 Series 5
From Halopedia, the Halo wiki
The Spectre action figure was different from the other vehicle sets in that it did not include any mini figures to go along with it. It featured a moving turret, along with an openable cockpit.
The Steel Spartan action figure had three different types, each with various detail coloring and insignias. It is armed with a Shotgun, Magnum, and a red CTF Flag, and featured 23 points of articulation.
On each action figure unit, Joyride has included a serial number, which allows you to find out when the action figure was created. The date code has four numbers followed by 'SS' actually stamped or embossed in the cardboard. The first three digits are the date the product was made, and the fourth digit is the year. For example: 2653SS means the product was manufactured on the 265th day of 2003 (9/23/2003).
