RX-1 Rail Gun

High powered weapon effective vs. armored enemies, fires super charged armor piercing ammunition.

Unlock Requirement
The Rail Gun unlocks at rank 14 (Major).

Upgrades
Unstoppable Rounds
 * A well shaped projectile coupled with extreme speeds gives a round that can pass through many enemies in a row before stopping. Larger and more heavily armored enemies will still stop the rounds as they can't defy physics.

Stun Rounds
 * Each bullet fired is loaded with a high yield electrical charge, that upon impact discharges and stuns the target for a while, enough to buy time for a second shot. The bullet is self charging and capable of delivering the charge to multiple targets if they are all hit.

Weapon Stats

 * Helldivers start with 4 magazines of Rail Gun ammunition, and can carry up to 8. Each magazine contains 5 rounds. If 1 round remains in the magazine when the weapon is fired, the 'low ammunition' warning sound will play.


 * Reload time for a fully emptied magazine is 2.5 seconds; if reloaded while there are still rounds in the magazine, this drops very slightly to 2.25 seconds. The Rail Gun is not capable of retaining a round in the chamber.

Gameplay Tips

 * A major difference between the Rail Gun and other weapons is that its upgraded Unstoppable Rounds travel through targets they damage, similar to how the SG-225 Breaker shotgun and the AR-20L Justice assault rifle function. Such weapons are somewhat less useful against the Illuminate's shielded units, since the shields must be downed before the shots will penetrate further.
 * Be wary of friendly fire: it is very easy to hit other Helldivers if proper firing discipline is not observed. This tends to occur most frequently when engaging enemies from both flanks at the same time. To maximize damage output, try to bait enemies into lining up (also known as 'kiting') so each shot will hit multiple targets in a row.


 * When upgraded with Stun Rounds, the RX-1's shots will temporarily immobilize even heavy foes like the large, armored bugs and the Cyborg Warlord -- as long as they are at least partially organic. Pairs well with the RL-112 Recoilless Rifle, M-25 Rumbler and EAT-17 as a result, and makes it much easier to get The Element Of Supplies trophy/achievement.


 * While it is effective versus most armored targets, the Rail Gun cannot destroy Cyborg IFVs or Bug Behemoths.
