Big Walk Walkthrough: Main Progression Route and Milestones

Big Walk’s main story is a chain of milestones, not one long fixed sequence of puzzles. This hub gives you the skeleton of a full run — tutorial beach, Drawbridge, the four colored towers, the Wall, the ending, and what comes after — and links each stage to its detailed node guide. The milestone names below are cross-checked against the Steam achievement list and multiple full-run records. Step-level details (exact puzzle counts, keys, and coordinates) live in the linked drafts and are still being verified in game.

The main route at a glance

Every complete run passes through the same backbone:

Stage	What it opens	Steam achievement	Detailed guide
Tutorial Beach	The Drawbridge	—	See Drawbridge guide
Drawbridge	The main island	Big Walk	Detailed coverage pending verification
Red Tower	Map Room	Big View	Detailed coverage pending verification
Green Tower	Chairlift	Big Sit	Detailed coverage pending verification
Blue Tower	Train	Big Ride	Detailed coverage pending verification
Yellow Tower	Tunnels	Big Tunnel	Detailed coverage pending verification
The Wall / Black Tower	Black Sphere sequence	Big Wall	Draft in progress
Ending	Credits and post-game	Big Goodbye	Draft in progress
Post-game	Purple puzzles, secret room	—	Draft in progress

The achievement names come from the Steam achievement list (checked on August 7, 2026), which confirms that the Drawbridge, Map, Chairlift, Train, Tunnel, Wall, and Ending beats are real progression milestones. The official FAQ confirms the game has a beginning, a middle, and an end, but does not publish a route — the stage order above is where platform data and multiple independent community full-runs agree.

On playtime: there is no verified completion time yet. Community reports range from roughly 12–14 hours for a focused main-line run to around 20 hours for thorough exploration, recorded under different group sizes and conditions, so the honest answer is that the range needs in-game verification before we publish a fixed number.

Tutorial Beach and the Drawbridge

Every run starts on a small beach area with four fixed puzzles. This is the only part of the game with a set sequence: finishing the beach puzzles opens the Drawbridge, earns the “Big Walk” achievement, and lets your group onto the main island. Multiple independent community guides and full-run recordings agree on this structure, and the achievement list confirms the Drawbridge milestone itself.

Do not skip the beach even if your group is impatient — it teaches the communication and coordination patterns every later tower relies on. Puzzle-by-puzzle steps, blorb locations, and the key-carving route remain in the verification queue until an in-game pass is complete.

The four towers in any order

Once you cross the Drawbridge, the route stops being linear. Community routes and full-run recordings show groups clearing the four towers in different orders, and each tower accepts puzzle rewards your group has already earned — so treat the order below as our recommendation, not a requirement:

1. Red Tower → Map Room (“Big View”) — unlocks the map room and a portable map, which makes every later tower easier to navigate.
2. Green Tower → Chairlift (“Big Sit”) — opens a lift that shortens long climbs.
3. Blue Tower → Train (“Big Ride”) — starts a train loop across the island.
4. Yellow Tower → Tunnels (“Big Tunnel”) — opens the tunnel network for fast underground travel.

The tower-to-system pairings above are consistent across several independent community guides and the full-run video record. Exact per-tower puzzle counts, key steps, and coordinates are community-reported and need in-game verification; each linked draft marks its own evidence status.

The Wall, the Black Sphere, and the ending

After the four towers, the route converges again. The Black Tower and the Wall form the next milestone (the “Big Wall” achievement), followed by the Black Sphere sequence and then the ending itself (“Big Goodbye”). Full-run recordings show these chapters in this order, and the achievement list confirms the Wall and Ending milestones.

What is not yet pinned down: the precise unlock conditions for the Wall and the Sphere, how objectives scale with your world’s player-count tier, and what the completion feedback looks like at each step. Those points are community-reported and need in-game verification — we will fill them in after a recorded full run on a fixed version.

Post-game and the secret room

Finishing the ending is not the end of the content. Community sources report that the post-game adds seven purple challenge puzzles, plus any puzzles your group missed during the main run, and that clearing them leads toward a secret room and an extended (true) ending.

Treat this section as the least-corroborated part of the route: the purple-puzzle count and the secret-room chain rest on lower-confidence community material and need in-game verification. We are keeping the claims visible so you know what to look for, but we are not presenting them as settled.

Full video walkthrough chapters

If your group wants to watch a whole run before or during play, the longest public full-play recording (by Levas, about 6 hours 43 minutes) is chaptered roughly as follows:

• 00:00 — Tutorial
• 03:19 — Map Room
• 1:58:18 — Chairlift
• 2:58:26 — Train
• 3:59:13 — Tunnels
• 4:55:29 — Black Tower
• 6:14:03 — Black Sphere
• 6:40:14 — Ending

Detailed guides in verification

The Drawbridge, Map Room, Chairlift, Train, and Tunnels drafts remain unpublished until their step-by-step routes complete an in-game verification pass.
