"This Skaarj weapon fires large, spinning, serrated blades capable of slicing through all but the toughest materials. The blades can alter their pitch and roll in accordance with transmitted motion signals from the RazorJack, giving them limited guidance.
Primary Fire: Single blades that ricochet off walls, ceilings and floors. Secondary Fire: Skilled users can employ english to alter the trajectory of blades after they leave the weapon."
In Unreal it's a type of weapon used by Skaarj troopers. It's first encountered on the ISV-Kran. The primary fire is, as with all Ripper family members, a fast moving, ricocheting blade that has the potential to headshot an enemy. However, unlike other similar weapons, the alternate fire is a homing blade that the player can guide with their crosshair.
Its ammo pack has the appearance of a small metal box, which opens up when the player gets near it.
