A Rorsch Mk-1 wielded by a Russian soldier in Karelia

The Rorsch MK-1 is a fictional prototype railgun in the Battlefield series, appearing in Battlefield 4: Final Stand.

Developed near the end of the War of 2020 by the Pan-Asian Coalition, the Rorsch Mk-1 fires a two-stage sabot round with an open-bolt operation. The projectile is fired into the Rorsch's electro-magnetic rails from a small cartridge, where is then accelerated and fired at a speed of 3600 meters a second. The first handheld weapon of its kind, the Rorsch suffered from a 3-second charge time and lengthy reload due its crude electrical operation, as its attached circuit breaker is blown each time the weapon is fired and must be reset before firing again.[1]

The weapon was likely the basis for the improved Rorsch Mk-S8 railgun emplacement later used by both the Pan-Asian Coalition and European Union during the Cold War of the 22nd century.

Battlefield 4Edit

"For safe handling of this experimental weapon it does not actively store its full charge. Once engaged, it takes a second to build up energy before discharging a heavy sabot round at extreme velocity. The operator must manually track moving targets during this charge time."

— In-game description

The Rorsch MK-1 is a battle pickup weapon featured in Battlefield 4: Final Stand.

The Rorsch fires a heavy sabot round at a very high velocity, and causes incredible damage on impact, always killing a player on contact. However, the weapon has a one-second charge-up before firing, and can only fire one round at a time, with the operator having to load another round into the gun after firing, with only seven rounds in reserve (the ammunition cannot be replenished). The weapon is equipped with a blue laser sight and a specially designed 20x scope, which displays the angle of elevation from the player, the player's directional heading in degrees, as well as the distance to the target. Notably, this scope causes Scope Glint like other Sniper scopes when aiming. When firing, the weapon's charging time is represented by three successive high pitched beeps and arrows pointing towards the crosshair in the scope.

Due to its charge up time, the player must track the target or predict their position. However, because of its incredibly high velocity, this is the only thing the shooter has to account for, as the projectile has no drop and will hit target almost instantaneously due to its travel speed. The charging time, while fairly short, can be a potential hindrance in close quarters combat, along with the very long reload time should the player miss, but the attached laser sight can offer some assistance in keeping enemies on target. The projectile's high damage also gives the player an edge in combat, as the round will always kill its target.

The Rorsch's projectile also causes a small explosion upon impact. This will cause splash damage to infantry around the target, and allows the weapon to be capable of attacking vehicles. The splash damage is capable of killing a player at full health if it hits very close to them, similarly to an anti-tank rocket. Against vehicles, the Rorsch is most effective against vehicles that are not heavily armored. The weapon is able to destroy light transports in two hits, and deals 20-40% damage against helicopters. Heavier vehicles like IFVs and MBTs should be avoided, as the Rorsch requires a significant number of hits to actually destroy them. The Rorsch's long reload time and small ammunition reserve will be a hindrance in combat with heavy vehicles.



  • Originally, no sound is played during the weapon's reload; this was fixed in the second beta of Final Stand.
  • Real railguns are caseless, firing a single projectile without the need for a cartridge case. The Rorsch fires a two-stage sabot round that is first fired into the weapon's rails by a small cartridge which is ejected after firing. This was a design decision done to give the weapon a reload reminiscent of the M1 Garand's characteristic "ping", so the two-stage round was added so a caseless firearm would actually be able to eject something.[1]
