How to get weapons

Weapons are sold in item shops across the game's five islands. At the start, only a small selection is available. Later islands add more weapons than the shops visited earlier in the run.

The earliest listed attachment is available on Island 2. Not every attachment works with every gun, and attachment prices can differ depending on the weapon being upgraded.

How to get Fully Equipped

Reach Island 3

Island 3 unlocks the group of attachments needed for the straightforward Pistol route.

Buy four attachments for the Pistol

Purchase and equip the following on one Pistol:

  • Laser Sight
  • Red Dot Sight
  • Compensator
  • Extended Mag

The listed total is $900. After all compatible attachment positions are filled on the same weapon, the Fully Equipped achievement should unlock.

How to equip and buy attachments

Hold the gun you want to upgrade before buying an attachment. Purchase attachments from upgrade or attachment shops, which begin appearing from Island 2 and are normally separate from the main item shop. Confirm compatibility before paying, because an attachment may fit several guns but not every weapon.
