The S8-Z "Grand Pinger" is a weapon in Army of Two: The 40th Day. This weapon, and the AS-KR1 can only be obtained by having a previous Army of Two save on your HDD. It was designed by Uberblargh, and was one of the winners of the pre-release Weapon Design contest.
It costs $450,000, the most expensive gun in the game. It has an undermount grenade-launcher and a Long Range 5X scope.
It was submitted as a joke by Operatorchan's /k/ board. The original image has the flashlight, vertical grip, ACOG scope, and box magazine facing backward and sports a paintball gun ammo hopper.
- It is interesting to note, that the M107 Sniper Rifle has a higher damage per bullet rate, as the AA-12 does than the Grand Pinger, and the AS-KR1.
