Main Path (Four Towers)
A focused co-op run — clearing the four towers (Red, Green, Yellow, Blue) and the Big Goodbye finale — is a weekend's worth of play for most groups. Because it's a talky co-op game, sessions are as long as your group wants to hang out; there's no forced grind.
The 100% True Ending
The 100% true ending requires the post-game seven purple challenges in the east-ridge area (reachable via the Green Tower chairlift). That adds a meaningful chunk on top of the main path — figure notably longer than a single playthrough, since the purple challenges are the hardest content. See purple challenges.
What Changes the Length
- Exploration — radio stations and shiny detours add time.
- Puzzle difficulty — the blue tower and purple challenges slow groups down.
- Group size — bigger groups (up to 12) can split tasks or get chaotic.
Co-Op Changes the Math
There's no single-player mode (see can you play solo), so "how long" always means "with friends." The walkthrough maps the route; the secret ending page covers both endings.
We avoid quoting exact hour counts we can't verify. Playtime varies with group style; treat the above as honest ranges, not measured figures.
