There aren’t that many weapons in StarRupture but the ones that are in the game feel powerful. With each new weapon you unlock, even more fire power is at your disposal. There are a ton of alien bugs in the planet, you already know the alien bugs (affectionately called “The Vermin”) don’t mess around. Your starting mining tool can barely tickle them, so unlocking proper firearms.

Pretty much every weapon in StarRupture is linked to Griffits Blue Corporation (the main combat & defense faction). There are two main methods to unlock new weapons in StarRupture.

You can compete contracts via the Corporate Terminal and Orbital Cargo Launcher. With these you will earn Warbonds that are then spent at the Equipment Upgrade Station (unlocked at Griffits Blue Level 4).

Unlock Requirements for Every Weapon in StarRupture

Early weapons come free from corporation levels. Later ones cost Warbonds, which you earn through Griffits Blue progression + looting ruins, corpses, and blue chests. Since the game is in early access, available weapon pool is limited but we expect more weapons to be added later on.

Lets go into detail on how to unlock each weapon.

UPP-7 Pistol (Your First Real Gun)

To get the UPP-7 Pistol upgrade Grifftis Blue Corporation reputation to level 2. Start by constructing your initial Orbital Cargo Launcher (OCL) right after the tutorial wraps up, then head to the Recipe Station to unlock essentials like Titanium Ingots and Wolfram Ingots.

Craft a batch of Titanium Sheets or Wolfram Plates and load them into the OCL for a commission, and ship them to Griffits Blue. Keep grinding these deliveries until you have 800 to 1000 points to reach Level 2.

The UPP-7 Pistol will unlock automatically. Complete with the Pistol Ammo recipe popping up in your Basic Item Printer. For ammo, simply combine Copper Ingots and Rubber, and craft stacks early to stay loaded.

Grenade (Your First Explosive)

Grenades are unlocked when you reach level 3 with Griffits Blue Corporation to unlock Grenades. The same process applies here as well. Keep shipping Titanium Sheets and Wolfram Plates, or swap in upgraded items as they become available.

As soon as you reach level 3 with Griffits Blue Corporation the grenades will be added to your inventory, ready to craft more via the Basic Item Printer using Explosive Charges (which tie into basic chemistry recipes you’ll unlock along the way).

Unlocking Advanced Weapons (MAR-9, SLAMS-12, M175 “GRIM”)

Advanced weapons like the MAR-9, SLAMS, and others are unlocked when you get access to the Equipment Upgrade Station.

The station in question is unlocked when you reach Level 4 in Griffits Blue Corporation which takes about 6K points. Scale up your game by automating production lines for Titanium Sheets and Wolfram Plates, erect multiple OCLs to ship in parallel, and claim your Level 4 rewards from the Corporate Terminal which hands over 120 Basic Building Materials. Use those to craft the station and plop it safely inside your base shield.

Once you have access to the Equipment Upgrade Station, interact with it and open the “Weapon Unlocks” tab to buy powerful advanced weapons including MAR-9, SLAMS-12, M175 “GRIM.”

Once unlocked you can craft these weapons using basic building materials. Each of these weapons have its own ammo type but those ammo recipes auto unlock when the weapon itself is unlocked.
