Big Walk Achievements — All 12 and How to Unlock Them

Big Walk carries twelve achievements, and most arrive naturally if you finish the island's five-key progression — but four are easy to leave behind, and the last one demands a full second lap. This guide lists every achievement with its exact unlock condition and the practical route to it.

General tips that pay for the whole list

• Talk constantly. The groups that finish fastest are the ones that never stop narrating. Assign each symbol or option a hand gesture early on — when a dozen same-type puzzles show up later, you answer in gestures without thinking.
• Visit the weather balloon. North of the green/blue towers, under the balloon itself, sits a unique wearable that lets you carry one extra blorb. Strap it on.
• Climb on each other. Grab-lift relays stack players higher and higher — the only way over some walls and up some ledges.
• Prefer tunnels, skip the train. The tunnel network moves you between regions fastest (a mountain shortcut also exists beside the golf blorb). The train is charming but slow and infrequent.

Story achievements — the five-key progression

Big Walk — "Cross the drawbridge"

In the starting region, collect 4 blorbs and bring them to the key device. Assemble the key, place it in one of the five key-cutting slots — the device's arrow then points you to the next slot — and finish the full key. Take it to the red bridge, slot it to drop the drawbridge, and step across. Full walkthrough in the drawbridge guide.

Big View — "Visit the map" · easy to miss

Bring 5 blorbs to the red tower, make the key, and carry it to the grand staircase beside the tutorial area. The key opens the map room — walk in for the achievement. It is one room most groups sprint past; details in the map coordinates guide.

Big Sit — "Ride the chairlift" · easy to miss

5 blorbs + the green tower = the chairlift key. Slot it at the station near the tower and board a cabin. Our chairlift guide has all five puzzle coordinates.

Big Tunnel — "Enter a big tunnel" · easy to miss

5 blorbs + the yellow tower = the tunnel key, which opens the yellow gates and the whole tunnel network. Step inside any tunnel entrance for the achievement.

Big Ride — "Ride the train" · easy to miss

5 blorbs + the blue tower = the train key. Start the monorail at the station and hop on a moving carriage. Route and machines in the train guide.

Big Wall — "Go beyond the wall"

After the five previous keys, the black obelisk gate opens. Bring 6 blorbs to the black obelisk for the black key, then take it to the gate in the great wall at the island's far west and pass through.

Big Goodbye

Past the wall, trek to the giant sphere, enter it, and solve its puzzles. Exit the far side to reach the finale, pass the last turnstile, and walk through the white door. The achievement pops when you quit the game after the ending.

Big Game — "Complete the game" (100%)

The true ending, and the long tail: collect the final 15 blorbs and bring them to the green building near the tutorial/map area. (All keys together consume 30 blorbs; 8 more red blorbs exist beyond that.) Behind the purple gate at the easternmost chairlift station, a challenge area unlocks — its puzzles produce purple blorbs, which appear on your map once you finish the game. Collect them all to receive the white key and return to the tutorial area, where the small black sphere has cracked open to reveal key slots. Head down the stairs, follow the prompts, and watch the true ending. The seven purple challenges are each broken down in our purple challenges guide.

The rest of the list

Big Pack — "Wear a backpack" / Big Help — "Wear something on your hip"

The island's blue spiral buildings (they look like parking garages) hold wearable gear — mostly backpacks early, belts later. Have a teammate strap a backpack on you for Big Pack, and a hip item for Big Help. Every location is in the backpack and hip pack guide.

Big Climb — "Reach the highest point"

Ride the chairlift from its unlock station one stop west to the highest-elevation stop on the map. The island's peak — a small dome structure — sits above it. Climb from that station to the very top. No reward waits up there, just the achievement and the view.

Big Makeover — "Get shiny"

Once the Big Tunnel achievement is done, find the hair salon inside the tunnel system — at the red/blue region junction near the party area, across a green bridge and down an Escher-style red staircase into the purple zone. Pick one of the three shiny colors at the bottom and have a teammate paint you with it. Step-by-step in the Big Makeover guide.

Miss-proofing the list

The four "easy to miss" story achievements (Big View, Big Sit, Big Tunnel, Big Ride) all share the same trap: the key exists, but nobody ever uses the thing it opens. Make it a rule — every time the group finishes a key, the very next stop is the thing it starts. Do that, and the only achievement that will need real farming is Big Game's blorb sweep.
