Kinetic Spike Projector KSP-3 'Railsplitter'

The KSP-3 is a single-use, emplaced area-denial weapon produced by Arcturus Defense Solutions, combining magnetic linear acceleration technology with a conventional fragmentation charge in a configuration that produces a directional, high-velocity fragment swarm rather than an omnidirectional explosion. The device is planted and oriented — typically flush against a wall, embedded in a road surface, or mounted to a structural column — and when triggered, a primary charge fractures a tungsten-carbide plate into approximately 340 irregular fragments while a linear magnetic coil array accelerates the swarm to 1,800 m/s across a 30-degree forward arc. The result is a wall of hyper-velocity fragments traveling faster than most personal armor is rated to stop, covering a kill corridor approximately 2 meters wide and 40 meters deep.

specifications

weight: 1.4kg (emplaced unit)
dimensions: 180mm x 120mm x 40mm
fragment count: Approximately 340 irregular tungsten-carbide fragments
fragment velocity: 1,800 m/s at muzzle, 900 m/s at 40m
effective arc: 30-degree forward cone
kill corridor: 2m wide, 40m effective depth
trigger options: Remote wireless, Tripwire (optical or physical), Pressure plate, Timer
emplacement time: Approximately 45 seconds for trained operator
armor penetration: Defeats standard-issue Level IV ballistic plating at 20m

tactical use

The KSP-3 is an ambush and area-denial weapon. Operators emplace multiple units along a predicted movement corridor — a hallway, a stairwell, a vehicle approach lane — and detonate them in sequence as targets enter the kill zone. A three-unit staggered deployment can cover 120 meters of corridor with overlapping fragment swarms, making advance through the area nearly impossible without armored vehicle support. Military units use them to hold defensive positions with minimal personnel; street operators use them to protect extraction routes or punish pursuing security forces. The 45-second emplacement time means they can be deployed during a running engagement.

cultural context

The Railsplitter is one of the few weapons in GLMZ that security analysts treat as a direct indicator of military-grade operational planning. Civilians don't use KSP-3s for robberies. Their presence at a scene indicates either a military unit, a contractor with military sourcing, or someone who spent enough credits on the black market to suggest institutional backing. In the aftermath of the Kessler Corridor Incident of 2194 — where a corporate extraction team emplaced nine KSP-3s in a residential transit tunnel, killing 34 people — the weapons acquired a specific political weight. Anti-corporate activist groups use the Railsplitter as a symbol of corporate violence against civilian infrastructure.

story hooks

A transit maintenance worker found a KSP-3 emplaced beneath a pedestrian bridge — it's been there for six months, still live, and whoever placed it never came back to collect it.
A corporate security contractor is selling decommissioned KSP-3s by claiming the magnetic coil array has been disabled — it hasn't, and the buyer is a neighborhood defense collective in a residential district.
An investigation into the Kessler Corridor Incident was closed without charges — a retired forensic analyst has documentation that the fragment signatures match a specific Arcturus production batch traceable to a named client, and she's looking for someone to take the case.

physical description

visual profile	A compact, angular rectangular block resembling a chunky breaching charge or mining explosive—utilitarian and deliberately unadorned. The device has a low, wide footprint designed for flush mounting against surfaces. Its industrial aesthetic reads as purpose-built military hardware: no curves, no compromise.
dimensions	180mm length × 120mm width × 40mm depth (roughly the size of a hardcover book stood on edge)
weight description	Deceptively dense for its size—1.4kg feels substantial and grounded in hand, with the weight biased toward the tungsten-carbide plate core. The heft communicates lethal payload despite the modest volume.
primary material	Reinforced polymer housing with internal tungsten-carbide fragmentation plate; magnetic coil array embedded in aluminum substrate
finish	Matte charcoal polymer with brushed aluminum accent panels around the magnetic assembly. Shows deliberate corrosion resistance—no chrome or polish, only functional coating.
color scheme	Gunmetal gray primary with dark charcoal polymer body; thin accent lines of brushed aluminum framing the linear accelerator aperture; no paint, all industrial coating
grip texture	Textured polymer edges with shallow grip indentations molded into the sides for two-hand handling during emplacement; cool aluminum contact surfaces on the mounting face
distinctive features	Linear magnetic coil aperture running the length of the device—a horizontal slot revealing aluminum ribbing and coil windings Tungsten-carbide plate visible through a reinforced window on the front face—dark metallic, fractured-pattern etched surface Three recessed trigger-type selector knobs (wireless, tripwire, pressure) on the top edge, unmarked except for subtle Morse-code-style notches Integral quick-mount bracket on the base with standardized NATO rail points Serial/batch code laser-etched into the rear: 'IPA-KSP3-447821' Faint heat damage and burn scoring around the magnetic aperture from testing/prototype use
manufacturer markings	Iron Point Ammunition logo (stylized spike through a cartridge) stamped on the top-left corner in recessed chrome. Arcturus Defense Solutions secondary marking in smaller font on the rear mounting face. No license plate; classified military hardware.
condition typical	Pristine or near-new when distributed, but field units show scoring from emplacement, dust/concrete residue in the aperture, and occasional scorch marks from detonation proximity. Never repaired—single-use item discarded after function.

Dramatic side-lighting from the left (cool blue-white 5000K) casting sharp shadows across the brushed aluminum accelerator assembly. Close detail shot showing the textured charcoal polymer housing, recessed trigger selectors, and laser-etched manufacturer markings. Background: out-of-focus industrial metal panels suggesting a weapons lab or armory. Neo-noir urban aesthetic: cold, clinical, lethal precision.
