We Were Here Tomorrow R&D Headquarters Walkthrough: Second Floor, Power and the Upgraded Prototype
On this page
What is verified on this page
This page is a launch-day scaffold from October 20, 2026. The places and trophies come from the Exophase story list in order; the segment label is this site’s grouping, not an official chapter title. The full route is on the walkthrough hub.
No preview played this far, so there are no verified puzzle steps here yet. Each solution lands on this page after a live co-op check in the released game.
Trophies on this route
The shortest story segment on the route: three trophies, then the route turns to the Temporal Research Centre. None are missable.
| Done | Trophy | Grade | How to unlock |
|---|---|---|---|
| Recon & Disclose | Bronze | Arrived on the second floor of R&D Headquarters | |
| Turn It Off And On Again | Silver | Restored power to R&D Headquarters | |
| Double Time | Bronze | Obtained an upgraded Norček prototype |
Two tools, two views of every puzzle
The two tools are chosen at the start rather than assigned by player number: TheGamesLayer’s hands-on describes picking between the Goo Gun and the Grabber, and the trophy list names the pair the Hook Gun and the Goop Gun (the Grabber is the hook tool). GameWatcher’s gamescom session had players swap roles mid-section.
So read the two sections below as perspectives, not fixed lanes: jump to the Hook Gun explorer (Grabber) or Goop Gun explorer section from the table of contents for your side of each puzzle.
Hook Gun explorer (Grabber)
- Verified tool facts only: the hook grapples to energized surfaces (Danger! High Voltage) and can hook your partner (Now I’m Hooked).
- Turn It Off And On Again restores power to R&D Headquarters. Whether the powered-up rooms expose energized grapple points for the hook side is one of the first things the live check will record.
- Detailed puzzle steps for this segment will be added after a live co-op check.
Goop Gun explorer
- Verified tool facts only: the Goop Gun makes goop blocks to weigh, boost, bridge or gunk with, and can lock your partner in place (You’re Chatty for a Statue).
- Double Time hands this segment an upgraded Norček prototype. What the upgrade changes for either tool is not in any preview; it gets described here after the live check.
- Detailed puzzle steps for this segment will be added after a live co-op check.
What both explorers need to know
- A checkpoint after each puzzle means you can bank Double Time and stop before the Temporal Research Centre (how long to beat).
- GameWatcher’s three questions are the fastest way through a power restore: how does it look, what does it do, and what is the sequence?
