The short answer
We Were Here Tomorrow takes about 15 hours to complete, according to the developers. That is the official figure from Total Mayhem Games' own announcement — not a community estimate, and not extrapolated from the earlier games.
What "15 hours" actually means for a co-op pair
Fifteen hours is a campaign, not an evening. For a two-player game this matters more than usual, because both players have to be present for every minute of it. A few planning realities:
- Calendar time will exceed 15 hours. Coordinating two schedules across several sessions adds friction. Real pairs should budget three to four weeks of casual-evening play, not one weekend.
- Communication speed sets your pace. The game is built on describing what you see to a partner who cannot see it. Pairs who narrate carefully solve puzzles steadily; pairs who rush burn time on misunderstandings. Your 15 hours depends heavily on how disciplined your callouts are.
- Stuck time counts. The developer figure presumably assumes a reasonable puzzle pace. If your pair hits a hard wall on one puzzle, an hour can vanish on a single room. See Stuck Help for a method to keep stuck time bounded without spoiling answers.
Main story vs. 100% trophy completion
| Run | Estimated time | Notes |
|---|---|---|
| Main story, steady pace | ~15 hours | Developer figure |
| Story + natural trophy pickup | ~16–18 hours | Site estimate, not an official figure — many trophies tie to story areas and co-op feats you will attempt anyway |
| Full 100% (all ~37–40 trophies) | Longer; not yet timed | Missable collectibles and co-op interaction trophies may require a second pass or deliberate detours |
| Second run, roles swapped | Faster than the first | You keep the puzzle logic; you relearn only your new side's perspective |
A note on the 100% row: the trophy list is confirmed at roughly 37–40 entries (see the trophies guide), but exact unlock steps are still being verified, so nobody can give you a reliable 100%-completion time yet. The pattern from the series is that a second playthrough with swapped roles — each player taking the side they did not play — is the natural way to clean up missed trophies.
Series comparison
The previous entry, We Were Here Forever, ran about 10–12 hours with 39 achievements. Tomorrow's 15-hour figure makes it the longest game in the series by the developers' own numbers. That matches the scope suggested by the trophy-derived location sequence — eight distinct areas from the Norcek opening through the Temporal Research Centre to the Rift — though that sequence is inferred from trophy descriptions, not from an official chapter list, and area names are not chapter divisions.
Coming from Forever? Budget about a third more time than that game took you, and expect the same co-op rhythm at a larger scale.
Session planning for co-op pairs
Until save behavior is verified for this title, both of you should be present for every session and neither player should progress alone — plan sessions like appointments:
- Agree on session length before you start. Two to three hours is the sweet spot for most pairs: long enough to finish areas, short enough that fatigue does not wreck communication.
- End sessions at area transitions, not mid-puzzle. Starting cold on a half-solved puzzle costs both players re-orientation time. The location sequence in the trophies guide gives you a rough sense of the game's area structure for planning breakpoints.
- Keep your shared notes between sessions. A five-minute recap at the start of session two saves thirty minutes of "wait, what were we doing." The beginner tips checklist covers this habit.
- Protect the calendar. The number one killer of co-op campaigns is not difficulty — it is two busy people failing to reconvene. Book the next session before you end the current one.
Replay value and the second run
The asymmetric design means a second playthrough is genuinely different: each role sees different spaces and uses a different ability. Players who finish once commonly replay with roles swapped, both to experience the other half of the game and to chase the trophies tied to the side they did not play. Whether the code or symbol content changes between runs is not yet confirmed — so do not plan a replay around that assumption.
