Heavy Railgun v04 CS-OneSOneK

The Heavy Railgun v04 CS-OneSOneK (usually called the Heavy Railgun) is a powerful rail weapon balanced by an extremely high cooldown, introduced in Plazma Burst 2 and made by the Civil Security.

Characteristics

 * Fires a powerful, hitscan rail projectile, hitting targets the moment the gun is fired.
 * Rails lose hitscan properties while underwater, but can regain them when they resurface.
 * Rails cannot pierce walls, but they can pierce through enemy targets.
 * Rails can be ricochet from any angle in Multiplayer Deathmatch and Team Deathmatch game modes, dealing slightly reduced damage per bounce.
 * Rails can also ricochet off of a Shieldnade in any game mode.
 * Compared to the Lite Railgun v01 CS-HShot, the Heavy Railgun trades off fire rate and accuracy for more power.
 * Highest power of all weapons, tied with the CS-GaussRifle.

When it is upgraded to level 3, it may sometimes make you become unstable due to its recoil power.

Location
The Heavy Railgun is first encountered in the campaign when a few Android SLC-56s equipped with it fight the player on Level 8. The gun is seen on a regular basis after level 8, usually upgraded to at least level 2. It cannot be picked up by the Marine or bought from the equipment shop. However, Proxy can pick up the weapon in level 30 from a crate and upgrade it in the equipment shop of Proxy. A fully upgraded Heavy Railgun can be picked up by any protagonist from a killed Civil Security Boss on level 40. This gun costs $2700 credits, and can be upgraded for $900 credits. The Heavy Railgun is moderately more expensive than the Lite Railgun.

Trivia

 * The Heavy Railgun can penetrate up to four bodies owing to its high projectile power.
 * The bulb on its upper-rear will start to glow as the gun reloads; a pure blue indicates the reloading process is complete.
 * When the game is paused while the bullet is moving underwater, the glow will fade and reveal that the railgun bullet is actually very small, possibly the smallest in the game
 * While the Railgun's shots do not seem to bounce off of surfaces as much in campaign, in multiplayer it is infamous for its ability to bounce off of almost every surface.
 * The letters OneSOneK may be short for One Shot One Kill, most likely a reference to its power.
 * On Impossible difficulty, all Heavy Railguns upgraded to level 2 or 3 will be replaced by the Sniper Rifle CS-YippeeKiYay, except the player's.
 * It has the highest projectile power of all weapons in the game with a projectile power of 8. This is significantly higher than the runner-up, the Sniper Rifle, with a projectile power of 5.
 * It is used by all ranks of the Civil Security, and almost every Usurpation rank besides the Minor, as well as the Android SLC-56. It is the only Civil Security weapon to be used by all ranks of the Civil Security.
 * It does a large amount of damage to Corvettes.
 * It features a distinct low hum when firing.
