</>What is Fly?
Fly turns Blue Prince into open airspace: flip it on and move in any direction you aim the camera, passing straight through walls and floors to reach corners of Mt.

A free mod from ProjectMods, the community-first modding platform.
</>Common questions about Fly
What does Fly do in Blue Prince?
Fly lets you lift off the floor in Blue Prince and glide freely in whatever direction you point the camera — up the grand staircase, straight through a wall, or high over the Mt. Holly grounds. Instead of being boxed in by the mansion's rooms and locked doors, you float wherever your curiosity leads. Look up to rise, look down to descend, and aim ahead to cruise forward. Flip it off any time to drop back into normal play. It is a free mod from ProjectMods, the community-first modding platform, and it turns the whole estate into open airspace you can explore at will.
How does the Fly Speed slider work?
The Fly Speed slider sets how fast you drift while Fly is active in Blue Prince. Slide it low for a slow, cinematic float — ideal for lining up screenshots or easing through a tight doorway — and slide it high to zip clear across the Mt. Holly estate in seconds. Your speed applies to every direction you move, so rising, descending, and cruising forward all share the same pace. You can adjust it mid-flight and see the change instantly, so there is no need to land or toggle anything off. Set it once to your taste, or nudge it as your mood shifts from careful scouting to a quick fly-over.
Can I fly through walls and floors in Blue Prince?
Yes. With Fly turned on in Blue Prince, walls, floors, and ceilings stop blocking you — you pass straight through them to reach spots the mansion's layout normally keeps sealed off. That means you can slip past a locked door, drop through a floor into the room below, or float outside the house entirely to view Mt. Holly from angles the level design never intended. Nothing about the building's geometry holds you back while you are airborne. Turn Fly off and solid walls return immediately, so you are only ever a toggle away from ordinary exploration whenever you want the mansion to feel grounded again.
Can I turn Fly off in the middle of a run?
Absolutely. Fly is a toggle, so you can switch it on and off as often as you like during a single Blue Prince run without restarting the day. Flip it on to soar up and scout the next wing, then flip it off the moment you want to walk a room normally and interact with it on foot. When you turn it off, you settle back onto solid ground and play exactly as you would without the mod. This makes Fly easy to dip into for a quick look around and just as easy to set aside, so it never gets in the way of a serious puzzle-solving session at Mt. Holly.
Why would I use Fly in Blue Prince?
Fly is perfect for scouting, screenshots, and satisfying curiosity in Blue Prince. Use it to preview which rooms sit beyond a wall before you commit, to capture sweeping shots of Mt. Holly from outside the mansion, or simply to reach the odd corners the estate was never built to show you. Content creators love it for smooth fly-through footage, and streamers use it to answer chat questions about what is really behind a given door. Because it toggles on and off freely, you can pop into flight for a moment of exploration and then return to a normal run. It turns the whole house into a place you can wander without walls.
