The Radar Jammer as it appears on the Vigilante 8: Arcade website.
The Radar Jammer is a power-up item that made its debut in Vigilante 8. The Radar Jammer power-up creates an alternate target that quickly trails the player as they move, and serves as a decoy target for homing projectile weapons such as the Intercepter Rockets. They are a yellow, oddly shaped Z object found randomly on any stage in both Vigilante 8 and Vigilante 8: 2nd Offense.
