From Halopedia, the Halo wiki
The Joyride Halo 2 Series 2 action figures were manufactured by Joyride Studios. They were released during October 2004. All figures except for the White Spartan are based on the characters from Halo 2.
The Master Chief Version 2 action figure was the second Halo 2 Master Chief figure to be released. The armor is more updated, and comes with a Shotgun and a Magnum. The Magnum has a removable magazine.
The Drone action figure was the first Drone action figure ever to be released. It stands around 10 inches tall, and is armed with a Okarda'phaa-pattern plasma rifle. The game however, only showed Drones wielding Plasma Pistols and Needlers.
The Ghost action figure is more updated then the figures in the Halo: Combat Evolved series. It comes with a mini Brute figure that stands three inches tall with 10 points of articulation and a Brute Shot.
The Warthog Version 2 action figure is based off of the M12 Light Reconnaissance Vehicle. It also includes two blue Spartans, each with 10 points of articulation and are three inches tall. It also includes two Battle Rifle. The two Spartans can be placed in the driver, passenger, and gunner positions.
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).
