RW-45 Ion Pulse Rifle

The RW-45 Ion Rifle is a weapon found in System Shock.

Overview
Prototypes of this advanced energy beam gun evolved from late-model beam sidearms. It delivers a powerful stream of ionic particles with more force than normal Blaster guns.

This weapon can only be found in the Alpha Grove inside the corporate briefcase. At high settings, the Ion Rifle does slightly more than 150% damage per shot compared to the Blaster, but at the expense of 200% energy consumption. Frequent use of the Ion Rifle would require excess stockpiles of Batteries or quick access to Power Stations.

Trivia

 * Most of the weapons' names in System Shock are derived from the initials of the game's makers. In this case, RW stands for Robb Waters.
 * The animation frame of this weapon firing is actually not shown in the game itself, even if present in the files. This applies to all versions except the Source Port update, where it can be enabled using "Show All Weapon Frames" Game Option.
