How you unlock every gun in Duels depends on which game you mean, because several games use that name. In the most relevant result I found for Murder Duels Roblox , the main method is buying and opening weapon cases like the Founders Case or Recruiter Case , then equipping the gun from your items menu.

Quick Scoop

  • Go to the shop or the main base.
  • Open the Cases section and buy the case that contains the gun you want.
  • Check the weapon list inside that case to see what can drop.
  • When you unlock a gun, equip it from Items.
  • Higher-rarity weapons are harder to get, so you may need to open multiple cases.

What this means

If you’re asking about Murder Duels Roblox , “getting every gun” usually means grinding cases rather than using a single unlock code or quest line. The guide I found says the process is basically: purchase cases, roll for weapons, then equip the ones you earn.
