The 12 Achievements
Big Walk ships with 12 achievements. The first seven are essentially the main story (tutorial + four towers + the Big Goodbye finale); Big Game and Big Pack require the post-game 100% route; and the final three are hidden flavour unlocks the community is still mapping out.
| Achievement | Type | How to Unlock |
|---|---|---|
| Big Walk | Opening | Complete the tutorial drawbridge and step into the open world. |
| Big View | Progression | Clear the Red Tower and unlock the Map Room. |
| Big Sit | Progression | Clear the Green Tower and unlock the Chairlift. |
| Big Tunnel | Progression | Clear the Yellow Tower and unlock the Tunnels. |
| Big Ride | Progression | Clear the Blue Tower and unlock the Monorail. |
| Big Wall | End-game | Carry 6 blorbs to the Black Obelisk, forge the Black Key, open the far-west wall gate. |
| Big Goodbye | End-game | Pass through the wall and reach the Black Sphere finale (normal ending). |
| Big Game | 100% | Complete the seven purple challenges and reach the true ending. |
| Big Pack | 100% | Collect the full set of blorbs / unlock all keys for 100% completion. |
| Big Help | Hidden | Community-discovered flavour achievement — exact trigger still being documented. |
| Big Climb | Hidden | Community-discovered flavour achievement — exact trigger still being documented. |
| Big Makeover | Hidden | Paint yourself (or a friend) metallic in the hidden tunnel salon. Verified two-player route: Get Shiny guide. |
Four Are "Technically Missable"
The four tower achievements (Big View, Big Sit, Big Tunnel, Big Ride) are flagged as technically missable — you can skip or reorder towers, but you still need all four cleared to reach the end-game, so in practice you'll earn them on the way. The progression-line ones (Big Walk through Big Goodbye) are the spine of the game.
Reaching 100%
For Big Game and Big Pack, finish the normal ending, then tackle the seven purple challenges in the east-ridge challenge area (reachable via the Green Tower's chairlift). Solving them yields purple blorbs, the white key, and the true ending. See the secret ending page for the step-by-step, and the walkthrough for the full challenge list.
Big Makeover is now verified — see the Get Shiny guide for the exact Yellow Lighthouse → tunnel salon route. Big Help and Big Climb are still being confirmed by the community; we'll update this table as verified methods surface (Steam Community Hub guides are the best source).
