MediEvil PS4 Remake / Remaster has 19 weapon locations. This guide shows where to find all of them. Some weapons are found throughout levels while others come from redeeming Chalices in the Hall of Heroes.

Finding all weapons unlocks the Master Dan-At-Arms trophy. None of them are missable! You can still get them via level select after the story. You can see which ones you found in the inventory. Press Touchpad to open the inventory and choose a weapon. After finding a weapon you must still finish the level for the progress to be saved (if you get a game over or quit the level you must get the weapon again).

To unlock the trophy you must have all weapons in your inventory at the same time. If a weapon gets stolen by an imp, you can rebuy it from a merchant gargoyle (or restart the level immediately when you notice that an imp stole from you).
