Last verified · TSC2 Wiki
A New Day introduces flooded Arkham and four locks: the fuse box, the 1908 house safe, the Star Key door in the church and the trident obelisk, plus the 1672 watergate. Budget around two hours, and sweep before the chapter closes.

Opening: the annex and the fuse box
The chapter starts you in a compact interior sequence that teaches searching, then hands you the first mechanical gate: the fuse box. Three fuses, three slots, shapes must match. All three fuses are in the immediate rooms, and the puzzle only looks broken when you are one piece short.
While you are here, sweep for the 1908 house safe. The code is the year on the radio shop sign outside — step into the street and look up at the storefront.
The flooded city and the boat
Once outside, Arkham opens up as a hybrid space: some streets are walkable, some are canals, and the boat is how you cross the rest. This is also where the game establishes that exploration is optional but rewarded — the fire department and the Silver Eel are not required, and both hold supplies.
One warning that comes from Frogwares rather than from us: do not ram the pier or structures with the boat. The studio's known-issues post lists boat collisions as a cause of a black screen that needs a save reload.
The church: Star Key, trident, obelisk
The centrepiece of A New Day is the church sequence, and it chains in a fixed order:
- Pull the gate lever and loot the corpse beside it for the Star Key.
- Open the churchyard outbuilding with the same key — there is an ERC crate inside. Remember it needs an activator pen.
- Unlock the upper church door and take the Trident from its mount.
- Solve the obelisk — snake, three-headed spear, arrow, horn, top to bottom — then stand clear for three lightning strikes.
- Return the charged trident to the same mount upstairs.
The crypts below the church are worth clearing while you are here; the Graveyard Key opens the route.
The watergate
The watergate takes 1672, the installation year cast into the nearby bell. Opening it re-routes the district and lets you finish the chapter's remaining errands.
The Gas Canister you pick up in this chapter is a progression item rather than a puzzle piece — carry it where the objective points and it resolves itself.
Before you leave A New Day
There is no chapter select. Clear this list first:
- The 1908 safe.
- The churchyard outbuilding ERC crate.
- The crypts under the church.
- The fire department and the Silver Eel.
- Every clue and document — early Dream Essence is what gets your first talents online in chapter 3.
The full version is on the missable checklist.
What comes next
Chapter 2, The Wake-Up Call, is the Printing House and the Devil's Reef Hotel. It is smaller than A New Day and takes most players longer, because it stacks five separate locks inside one building.
