Devil May Cry HD Collection

Lucia has three guns to collect:

• The Darts are in mission two. When you have to navigate platforms after getting the Aerial Heart you'll notice one platform has a statue and a blue orb fragment. The Darts are inside the statue.
• The Crankybomb is in mission five. If you play through as Dante, they're in the exact same place as the missile launcher - in the cargo hold of the plane.
• The Bowgun is towards the end of mission six. There is an underwater section and a door that, when opened, ends the level. The Bowgun is in the underwater section.
