ARC-920 railgun

The Asymmetric Recoilless Carbine-920 (abbreviated ARC-920 or known simply as the Railgun) is a compact-channel linear accelerator weapon used by the United Nations Space Command. It was designed and manufactured by Acheron Security.

Design details
The weapon needs to be charged before firing its high-explosive projectiles accelerated to an incredible speed. The explosive yield contained in the round adds to the kinetic force of the impact, making the weapon effective against both infantry and armor.

The weapon lacks zooming capabilities.

Gameplay
Compared to the Spartan Laser, the ARC-920's charging time is half the duration and deals less damage to vehicles. In addition, the travelling time for a fired shot is almost instantaneous.
