The RX-Rail, also known as the ST8 MKIII Hyper Railgun, is a next-generation electromagnetic superweapon developed by Tan Industries, specifically under the engineering leadership of Harold S. Tan. It is one of the most powerful and symbolically significant weapons in Tan Industry’s arsenal—technologically advanced, emotionally charged, and politically volatile.

Overview

The RX-Rail (also called the ST8 MKIII Hyper Railgun) is a prototype ontokinergy-based railgun further developed by members of the Tan Military Production Division in Tan Industries, capable of reducing any target down to its basic atoms in a matter of seconds. The RX-Rail is equipped with two firing modes depending the ammunition inserted: a burst equivalent to the power of a shotgun, and a powerful burst equivalent to shooting a RPG. The energy is powerful enough to disintegrate matter at a molecular level.

Functional Capabilities

  • Kinetic Devastation: It can launch ultra-dense slugs that shatter fortifications, tanks, mechs, or even orbital objects through sheer velocity.
  • Non-Explosive Impact: It does not require an explosive payload as the force alone obliterates targets while avoiding fallout.
  • EMP Backwash: The electromagnetic fields can temporarily disrupt electronics within a small radius of the firing point.

Designs

Standard RX

The design of the Standard RX-Rail is a matte color design with a cyber-AI digital sight which consist of a range finder and auto-calculation (an AI feature which calculates the ammunition and distance needed to hit the target).

T-RX-Rail

The design of the T-RX-Rail consists of a RSCP foundation designed RX-Rail, with T11167's old RSCP Foundation coat and his name being etched on the side of the railgun. This version consists of the range finder, auto-calculation, and even automatic fire when locked on target.

Civilian Use

The RX-Rail, due to it's highly advanced and danger if used in the wrong hands, the GFA reports that over 800 instances are used illegally by citizens. One such was Bloxstralian hitman and BloxTuber, Mr Skim.

Trivia

  • The T-RX-Rail was made in memorial for the death of Harold S. Tan's first son, T11167.
  • The company originally drew concepts for an anti-aircraft cannon variant, but were stolen by D.O.R, the plans were used to construct their Velkian facility's Gun Deck
