Weapons & Upgrades

A big cartoon arsenal and a tier-based upgrade bench drive these four. Collect the guns, pour resources into them, and grab the prize-machine ray-gun — including the two Gold trophies for maxing every weapon and unlocking the X1 D-Mousifier.

GoldFull guideCollapse

Upgrade every weapon to tier 3.

TypeGold
MissableNo
Difficulty5/10
EffortGrind

What it asks

Take every weapon in your arsenal to its maximum tier 3 upgrade.

How to earn it

  1. Collect the weapons first (see Guns, Lots of Guns).
  2. Earn upgrade currency and parts through combat and exploration, then pour them into each weapon at the bench until all are tier 3.
  3. Prioritise the guns you actually use so the grind doubles as combat progress.

Pro tips

  • Spend everything before the finale — leftover currency is wasted toward this.
  • Check whether any corporate-locked weapons must be unlocked first to count.

TypeBronze

What it asks

Acquire every weapon that isn't behind the corporate-locked condition — i.e. the standard obtainable arsenal.

How to earn it

  1. Pick up new weapons as you progress and explore side areas for the rest.
  2. Corporate-locked weapons are excluded, so you don't need those here.
  3. Check your weapon wheel for any gaps and backtrack with level select.
