The Kree sentry for the Cepheus Engine role-playing game & Other 2d6 Classic Science Fiction rpg

 To bring the classic cosmic menace of a Kree Sentry (like Sentry 459) into your Cepheus Engine space campaign, we have to scale it as a highly durable, high-Tech Level (TL 15+) heavy security unit.

In Cepheus Engine terms, this is a giant, heavily armored humanoid combat robot designed to watch over lost alien outposts, survive for millennia, and crush intruders with energy blasts and sheer physical force.

Offensive & Defensive Systems

Optical Disintegration Ray (Eye Beams)

A head-mounted, high-intensity plasma projector.

• Range: Personal (150m) / Extreme (400m)

• Damage: 5d6 Energy (ignores first 6 points of Armor)

Pneumatic Shock-Blasts (Palms)

Built-in atmospheric exhaust turbines in the hands that can compress and release hurricane-force kinetic blasts.

• Range: Close (10m) / Short (30m)

• Damage: 3d6 Kinetic (does not penetrate armor, but target must roll DEX or be knocked prone and pushed back 2D6 meters).

Sentry Melee (Fists/Stomp)

Massive metallic limbs striking with hydraulic-driven momentum.

• Range: Melee

• Damage: 3d6+5 Bludgeoning

Impenetrable Force Field (Colloidal Barrier)

The Sentry can project an energy dome up to 10 meters in diameter around itself or a targeted containment area to trap foes.

• Mechanic: Creates a physical barrier with 50 temporary HP. The Sentry cannot fire its Optical Disintegration Ray while maintaining this field.

Tactics & Campaign Use

• The Sleeping Giant: A standard hook involves the Travellers exploring an ancient, seemingly dead moon or a lost temple in a remote star system. When they attempt to salvage high-tech alien components, their tools trigger a silent alarm, and the stone-like monolith in the center of the chamber begins to glow with cold blue light.

• Implacable Pursuit: Kree Sentries have basic programming: Observe, report, and eliminate threats to the outpost. If the Travellers steal an artifact, the Sentry will hunt them back to their starship, ignoring non-lethal weapons and shrugging off laser rifle fire like rain.

• The Beacon: Striking down the Sentry should feel like a major victory, but the real threat is its final transmission. In its dying moments, it broadcasts a high-priority distress signal directly into deep space. Within 2D6 days, a Kree Scout or Cruiser will jump into the system to investigate.
