Big Walk: How to Find & Wear the Backpack

The backpack in Big Walk is one of the game's most useful items, because it is how you carry extra things — like a red blob — without using your hands. The short version: find one of the blue spiral structures dotted around the map, go inside to the pole where a backpack hangs, pick it up, and attach it to a friend's back (you cannot do this alone — one player wears it, the other attaches it). The moment it goes on, the backpack achievement pops. After that, the wearer can carry an item on the backpack, and a second backpack lets you carry two things at once.

The unlock at a glance

1. Find a blue spiral structure. These are the landmarks that mark a backpack's location.
2. Go inside to the pole. The backpack hangs on a pole inside the structure.
3. Free your hands and pick it up. Drop whatever you are holding first, then grab the backpack.
4. Attach it to a friend's back. It is a two-person action; the wearer does not attach it to themselves.
5. Carry items on it. Place a red blob (or another held item) onto the backpack so the wearer carries it.
6. Add a second backpack to carry two. A second backpack on the other player lets you move two blobs at once.

Before you start

You need two players. The backpack is a cooperative item — one player wears it while the other picks it up and attaches it, then you swap so both of you can be wearing one. It also helps to already be holding (or have nearby) a red blob, since the source demonstrates the backpack by loading a red blob onto it. There is no solo path shown in the source; the whole demonstration is two friends handing the backpack and items back and forth.

Success check: you have a second player with you and can see a blue spiral structure in the area.

Step 1 — Find a blue spiral structure

Look for a blue structure shaped like a spiral. The source is explicit that you are hunting for "these blue structures, the spiral blue structures". They are the visual marker that a backpack is nearby, and there is more than one around the map, so whichever one you reach first works.

00:16 — the spiral blue structure; find one of these and the backpack is inside.

Success check: you are standing at a blue spiral structure.

Step 2 — Go inside to the pole and take the backpack

Walk inside the structure. Inside it you find a pole, and on the pole hangs the backpack. Before you grab it, drop whatever you are carrying — the source drops a red blob first so both hands are free. Then pick the backpack up.

00:24 — inside the structure, the backpack hangs on a pole; grab it from there.

00:31 — the source drops the red blob first, then picks the backpack up.

Success check: you are holding the backpack in your hands.

Step 3 — Attach the backpack to a friend's back

With the backpack in hand, walk up behind your friend and attach it to their back. It is a handed action — you carry it and place it on the other player; the wearer does not put it on themselves. The instant it is attached, the backpack achievement unlocks. Then have your friend do the same back to you, so you are both wearing one.

00:36 — placing the backpack behind the friend; this is what triggers the achievement.

00:40 — the backpack achievement pops the moment the pack goes onto the friend.

Success check: the achievement notification appears and your friend is now wearing the backpack.

Step 4 — Carry an item on the backpack

The point of the backpack is to haul items. Pick up an item — the source uses a red blob — and place it onto the backpack on your friend's back. The wearer now carries that red blob hands-free while the two of you keep walking.

01:12 — the red blob goes onto the backpack, and the wearer carries it without using their hands.

Success check: the red blob sits on the backpack and your friend carries it as you move.

Step 5 — Add a second backpack to carry two

For heavier trips, use two backpacks. Your friend can also wear a second backpack and place another item on you, so together you carry two blobs at the same time. The source shows this exact setup, then heads off toward the tower with the blobs loaded up.

01:24 — a second backpack lets the pair carry two red blobs at the same time.

Success check: both of you are wearing backpacks and two items are loaded between you.

Step 6 — Take items back off the backpack

When you reach the drop-off — the source carries the blobs over to the tower to deposit them — pick the item straight back off the backpack the same way you loaded it. Nothing is locked in; you can load and unload the backpack as many times as you need.

01:43 — the blob comes straight back off the backpack when you grab it again.

Success check: the item is off the backpack and ready to be deposited or re-loaded.

Success check

You found a blue spiral structure, took the backpack from the pole inside, attached it to a friend, and unlocked the backpack achievement. From here you can load red blobs onto each other's backpacks and walk them to the tower, adding a second backpack whenever you need to move two items at once.

Common mistakes and recovery

• Trying it solo. The whole mechanic is two-person: one player wears the backpack while the other attaches it and loads it. Bring a friend.
• Grabbing the backpack with full hands. You cannot juggle an item and the backpack at the same time. Drop what you are holding (the source drops a red blob) before you pick the pack up.
• Looking in the wrong spot. The backpack is not lying on the ground — it hangs on a pole inside the blue spiral structure. Find the spiral landmark first.
• Forgetting the second backpack. One backpack carries one item; load a second backpack when you need to move two blobs to the tower in a single trip.
• Not unloading at the drop-off. The blob stays on the backpack until you pick it back off. Grab it again at the tower to deposit it.

Player-count and version notes

• The source is a two-player session, and every step shown is a two-player action: attach, load, and swap. The article does not assume a solo path because the source never shows one.
• The backpack works with red blobs in the source's demonstration, and the source describes carrying a ball / lantern object the same way, so it applies to held items generally — but the article sticks to what the footage actually shows (red blobs being loaded and carried).
• The blue spiral structures repeat around the map, so the exact one you reach first does not matter; the mechanic is identical at each.
