Unlock Every Gun and Apply Weapon Upgrades and Mods in StarRupture

What to know

• Unlock base guns like the UPP-7 Pistol at Griffits Blue Corp level 2, with advanced rifles and shotguns available after level 4 via the Equipment Upgrade Station.​
• Warbonds, earned from loot, bodies, and corp levels, buy weapons and mods that boost damage, recoil control, and range.​
• Attach mods at the Equipment Upgrade Station to customize firepower for Rupture waves and alien threats.​
• Grenades unlock free at level 3 for explosive utility, no Warbonds needed.

StarRupture's weapon system ties directly into your corporate progression on Arcadia-7, letting you build a lethal arsenal against escalating alien hordes. You'll start basic but scale up with targeted mods for every playstyle, from precision sniping to room-clearing blasts.

Unlock the Equipment Upgrade Station first

Reach Griffits Blue Corporation level 4 to access advanced weapons and modding. Build supply lines for Titanium and Wolfram ores, then construct a Smelter and Fabricator. Unlock Titanium Sheet or Wolfram Plate recipes, fulfill a commission via the Orbital Launch Station, claim rewards, and spend 120 Basic Building Materials to craft the station.​

You interact here to buy guns, mods, and apply attachments—essential for surviving deeper biomes.​

Gather War Bonds efficiently

War Bonds fuel your upgrades, so farm them relentlessly. Loot containers scattered across Arcadia-7, check dead bodies for drops, and hit corp milestones like level 5 (60 War Bonds), level 7 (80), and level 10 (100).​

Progress feels rewarding as these stack up during Rupture defenses and exploration.​

All gun upgrades and costs

Equip mods to slots for barrels, sights, magazines, and stocks, tailoring each gun's handling. Free mods unlock immediately; others cost Warbonds. Here's the full breakdown from the latest early access build.​

MAR-9 Phantom rifle upgrades

SLAMS-12 shotgun upgrades

M175 “GRIM” machine gun upgrades

Note: UPP-7 Pistol has no mods yet; Grenades can't be upgraded.

How to apply weapon mods

Access the Equipment Upgrade Station, select your gun, and slot available mods into categories like barrel or stock. Swapping costs minor resources but lets you adapt mid-game—swap to piercing for armored bugs or extended mags for waves.​

Test configs during lulls to optimize for your base's defenses.​

Rewards from weapon progression

Upgrading pays off beyond combat: stronger guns speed up clears, netting more loot and faster corp levels for extra Warbonds (up to 240 by level 10). Modded loadouts unlock harder contracts with premium payouts.

Prioritize the MAR-9 Phantom early for versatility, then mod the GRIM for wave suppression as threats scale. You'll dominate Arcadia-7's chaos with this setup, turning defense into offense.
