The Tek Railgun is an end-game ranged weapon introduced in Aberration and also available on Extinction, Genesis: Part 1 and Genesis: Part 2. It is the upgraded version of the  Fabricated Sniper Rifle and part of the Tek Tier item set.


The Tek Railgun fires explosive plasma blasts. While firing, it consumes  Element, each piece supplies the rifle with 2 shots.

Much like the  Tek Rifle, it does not need to be reloaded at any time, but unlike the rifle, it will overheat after every single shot and has to cool down before it can be used again. It is worth noting that the Tek Railgun cannot be fired underwater, whereas the Tek Rifle can be.

The Tek Railgun has a built-in scope lens that increases the sight range when activated, similar to the  Scope Attachment for lower-tier guns. The scope lens also has a heat signature tracking function, allowing the scope to identify living creatures by tracking heat signature. To zoom in while aiming, use the scroll wheel.

It also has a toggleable x-ray feature, which can be used to see creatures through walls (under a purple hue), but this feature will consume the durability of the supplied Element, at a rate of 3%[citation needed].

This weapon also has a very powerful piercing ability, capable of shooting through 5 metal behemoth gates and killing a person on the other side.

It is not recommended to use the Tek Railgun as an all-around weapon, as it takes a very long time to cooldown. The Tek Railgun is very bad with swarms, and should be used on high health targets you seek to kill.

The Tekgram is unlocked by either defeating  Alpha Rockwell or the Desert Titan.


  • The Tek Railgun Bullet has a limited Range of 10000 UE units which means bullets will disappear after ~ 33 Foundations and won't hit targets behind that.
  • The Tek Railgun loses 1 durability every 20 shots and an additional 4 durability each time a shot pierces a mineable resource such as small trees.
  • May also be rewarded from the Home is Where the Pouch is mission on Genesis.


  • on Xbox the Tek Railgun will not hit your target and will instead hit yourself dealing no damage.
  • On Switch you can't seem to fire the Tek Railgun even if you unlock it. You will be able to pull it out and use its thermal and x-ray abilities, but you can't fire it. (Looks like this has been fixed)
