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 | Community-discovered flavour achievement — exact trigger still being documented. |
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.
The exact triggers for Big Help, Big Climb and Big Makeover are still being confirmed by the community. We'll update this table as verified methods surface (Steam Community Hub guides are the best source).
