How Weapon Unlocking and Tier Upgrades Work?

Before looking at specific weapons, it’s important to understand the core progression system:

Mission Progression Unlocks Weapons

All base weapons in MOUSE: P.I. For Hire are unlocked through completing missions. There are no random drops or hidden vendors to chase. As you progress through the story, new weapons naturally become available.

Schematics System Powers Upgrades

Once the Schematics upgrade system becomes available (typically mid‑campaign), you can start spending collected schematics to upgrade your weapons. Each weapon generally has three tiers of upgrades that enhance performance, durability, ammo capacity, recoil reduction, and damage output.

Strategic Upgrade Choices Matter

Not every weapon should be upgraded equally. It’s usually more efficient to fully upgrade your core weapons (the ones you use most) rather than spreading resources thinly across all guns, especially early on.
