Arsenal upgrades strengthen your fleet by increasing gun damage, engine speed, armor strength, and shield density. You can obtain these upgrades by defeating bosses in combat sectors and then install them on your ships.
All 44 upgrades are grouped here by mining sector: the Barbarians sector—basic upgrades that enhance a single stat; the Pirates sector—paired upgrades that enhance two stats at once; and the Devastators sector—the most powerful upgrades, which provide several bonuses at once.
Open the upgrade card to see exactly what it enhances.
Installed on the fleet
An upgrade module is installed on ships and boosts their combat stats in every battle.
Upgraded with parts — at a risk
Improved with parts on a chance of success. On a failure, part of its power is lost.
Stabilizers — the safe way
Stabilizers give a second chance on failure — the most reliable way to upgrade.
Where to find
In three combat sectors of the Expedition — from wins and bosses: Barbarians, Pirates, Devastators.
Arsenal slots — how many upgrade modules you can equip
The arsenal has 14 slots. The 1st is free, slots 2-11 are bought for dark matter (price rises to 800,000 DM), and the last 3 for star ore. Slots 9-11 also require beating the Barbarian, Pirate and Devastator factions to stage 20 / 25 / 30. Each slot lets you keep one more upgrade module active on the fleet.

Arsenal points — how they are calculated
Every upgrade gives arsenal points: points = tier × level × 100, where the tier is 10 / 20 / 40 for Barbarian / Pirate / Devastator modules. Only your best modules count — as many as you have open slots. The overall maximum is 3 000 000 points.
