In Warhammer 40,000: Space Marine 2, unlocking and upgrading weapons is crucial to ensure you can effectively combat the relentless waves of Xenos and Chaos. As a Space Marine, you'll have access to a wide array of powerful Astartes weapons, but knowing how to unlock and upgrade them is essential to prepare for every threat.

Whether you are fighting alone in campaign mode or with friends in co-op, weapon upgrades will help you overcome all sorts of challenges easily. If you want to know more about unlocking and leveling your weapons, read this guide.

How to Unlock Weapons in the Campaign Mode

In the single-player campaign mode of Space Marine 2, you will start with a few basic weapons. But as you progress, you will unlock more weapons. Once you have completed your first mission, you can access the Armouring Hall. In this hall, you can choose your loadout before future missions.

To unlock new weapons in this mode, you will need to progress through the storyline and complete missions. However, some weapons are locked behind specific challenges or achievements, requiring you to meet certain criteria. Thoroughly explore each area and complete side objectives to unlock these exclusive weapons.

How to Unlock Weapons in Operations Mode

In Operations Mode, you'll begin with all weapons unlocked in their base form, immediately giving you access to various tools. However, these weapons will be in their basic state. To unlock advanced versions and stronger upgrades, you'll need to earn Weapon XP. This progression system allows you to gradually improve your arsenal, enhancing damage output and gaining new features as you level up each weapon.

To unlock armor sets, you’ll need to complete specific missions, regardless of their difficulty. The good news is that once you finish the mission, you’ll unlock the entire set without hunting them down separately.

How to Upgrade Weapons

To upgrade your weapons and armor to the Master-Crafted level, you’ll need to gather *Armory Data*. There are three types of Armory Data:

  • Green for Master-Crafted items.
  • Purple for Artificer tier.
  • Gold for Relic tier.

Once you’ve unlocked a new tier, you can continue accumulating XP to further advance to higher levels within that tier, enhancing your gear’s power and capabilities.

When you unlock the new tier, you will see that a better version of the weapon is available. You can again use Weapon XP to stack up the first tier and use Armory Data again to unlock more advanced versions and keep progressing.
