Grave Protocol Arms Entropy Pistol EP-1 'Half Life'

A compact directed energy weapon that fires a focused beam of accelerated beta particles — essentially a handheld radioactive emitter that delivers a lethal radiation dose to a targeted area. The Half Life produces no visible beam, no sound, and no immediate physical effect. Targets exposed to the beam develop acute radiation syndrome over the following hours to days, with lethality depending on exposure duration.

Grave Protocol Arms — the same phantom manufacturer behind the Terminus railgun — produced the Entropy Pistol for a purpose that even veteran intelligence operators find disturbing: a weapon designed to kill slowly, painfully, and with no possibility of treatment. Acute radiation syndrome from EP-1 exposure follows a characteristic progression — nausea, then apparent recovery, then catastrophic organ failure as the irradiated tissue dies.

The weapon is the size of a large handgun and looks like nothing more than a matte-black tube with a trigger. There are no controls, no sights, and no indicators. The weapon either fires or it doesn't, and the target either dies in three days or survives with cancer they don't know about yet.

specifications

caliber: N/A — focused beta particle beam
effective_range: 2-30 meters
rate_of_fire: Continuous beam, 3-second exposure for lethal dose
capacity: 40 lethal-dose exposures per sealed source
weight: 1.8 kg
power_source: Sealed radioactive source, 10-year operational life

tactical use

The Entropy Pistol is deployed for deniable eliminations where the time between exposure and death provides operational cover. An operator can irradiate a target in a crowd, leave the area, and be on the other side of GLMZ before the target shows symptoms. The weapon's lack of visible or audible signature makes detection impossible without dedicated radiation monitoring equipment, which is not standard in most security configurations.

cultural context

The EP-1 represents the most ethically condemned weapon in GLMZ's arsenal. Radiation weapons were prohibited by pre-collapse international treaty, and their use carries the only weapons charge that can result in universal jurisdiction prosecution — meaning that any entity, corporate or governmental, can claim authority to pursue the user. Despite this, Grave Protocol Arms continues to produce the weapon, and its occasional use is documented by the unexplained appearance of acute radiation syndrome in individuals who had no exposure to known radioactive materials.

known users

Unknown — possession alone carries capital charges

story hooks

A hospital is treating three patients with identical acute radiation syndrome — all attended the same corporate gala five days ago. Someone walked through the party with an Entropy Pistol, irradiating targets at a social function. The guest list is 400 names long.
A Grave Protocol Arms Entropy Pistol was found in a dumpster, still containing its sealed radioactive source. The weapon has been fired recently — the source decay pattern indicates dozens of exposures. Someone has been using it regularly, and the victims may not know they are dying.

physical description

visual profile	A minimalist tube pistol with the aesthetic of a suppressed weapon, but stripped of all external complexity. Sleek, utterly devoid of ergonomic flourishes or tactical attachments. At first glance, it could pass for a compressed air tool or industrial device rather than a firearm. The form factor suggests function over form, but with an unsettling clinical precision.
dimensions	18 cm length, 4.2 cm diameter tube, 2.8 cm grip width. No protruding barrel or slide — the entire structure is a unified cylinder with a trigger assembly.
weight description	Dense and compact despite modest size — 1.8 kg feels concentrated, heavy for its volume. Gives the impression of mass concentrated in the core rather than distributed. Sits in the palm with an unsettling dead weight, like holding a sealed container of consequence.
primary material	Aerospace-grade tungsten alloy core wrapped in carbon-composite external casing. The internal structure is purpose-built shielding.
finish	Matte military black polymer exterior, slightly textured to prevent light reflection. The seams where the casing meets internal components show minimal gaps — obsessively precise manufacturing. No gloss, no shine, designed for invisibility.
color scheme	Flat black primary with silver-gray accent lines at the trigger assembly and the sealed radiative source cap at the rear. The color is absence rather than presence.
grip texture	Minimalist textured polymer grip, aggressive micro-serrations for retention in wet conditions or when hands are shaking. No palm swell or finger grooves — the grip is deliberately uncomfortable, forcing conscious control.
distinctive features	Rear-mounted sealed source cap with minute radiation hazard symbol etched into the material Single mechanical trigger with unusual resistance — requires deliberate intent to depress No safety mechanism visible or apparent Trigger assembly frame appears to be titanium-reinforced, suggesting custom trigger work Minimal laser-etched serial number on the undersurface of the grip Subtle heat vents along the lower cylinder, barely visible until magnified The muzzle end is completely flush — no barrel shroud, no device attachments possible
manufacturer markings	Grave Protocol Arms logo — a stylized hooded skull overlapping the Greek letter Φ — laser-etched in micro-detail on the left side of the grip. Serial number stamped beneath the polymer on the right grip panel. No other identification. The logo itself is nearly invisible unless light hits it at a specific angle.
condition typical	When fielded, the Entropy Pistol maintains pristine condition. Operators treat it with obsessive care — there is no 'battle-worn' variant. Storage in lead-lined containers means minimal external wear. If one is encountered in the wild, any surface damage is unusual and suggests recent, hasty deployment.

Grave Protocol Arms Entropy Pistol EP-1 'Half Life' product photography: sleek matte-black tube pistol with titanium trigger assembly, photographed on dark brushed steel surface under dramatic side-lighting that catches the minimal silver accents. Single gloved hand (tactical leather, slight perspiration visible) holding the compact weapon with two fingers on the trigger guard, showing the flush muzzle and sealed rear cap. Micro-etched manufacturer logo visible on grip in harsh side-light. Neo-noir urban aesthetic: cool blue and amber rim-lighting emphasizing the clinical, purposeful design. No unnecessary details, no ergonomic softness — pure lethal intent rendered as industrial minimalism. Shot from 45-degree angle to emphasize compact profile and weight concentration. GLMZ warehouse aesthetic — corrugated metal backdrop, subtle neon reflection in the black finish. --ar 3:2 --v 6
