Level 15 — Riverside
Video Walkthrough
Objective
Finish Riverside by outfitting the sewer–shore loop: grab batteries and a branch, take the first red triangle from the notice board, find the UV light in the trash, read III V IV IX as 3549 to enter the storeroom, collect the cabinet key and scissors, trace the UV poster into the metal case wiring puzzle for the green triangle, head riverside for tape and a fishhook, build the Reaching Branch to snare the blue triangle from the high cage, power the yard at the electrical box, mount all three colored shards, then repeat the button colors shown near the breaker so the hidden ladder drops and the level completes.
Step-by-Step Solution
Cold open. In the underdrain gallery, pocket a battery (or pair) plus a stout branch from the rubble. Outside the storeroom airlock, read the notice board—peel away flyers until the first red triangular shard sits in inventory.
Ultraviolet salvage. Comb the yard dumpsters until you recover the UV lamp (or blacklight wand). From this moment every chalky wall and glossy poster is suspect—keep it charged with the cells you found.
3549 gate. Sweep the concrete sump with UV: Roman numerals III · V · IV · IX phosphoresce in order. Translate straight into 3-5-4-9, type 3549 on the storeroom membrane, and step through when the bolts thunk open.
Stockroom raid. Inside, slash cardboard towers for the electrical cabinet key and a pair of scissors. Angle the UV across the wall poster again; a dotted color trail or node graph appears—sketch it before the glow fades.
Emerald trace. Open the metal crate’s touch panel and draw the connector path exactly like the poster: completing the route drops the green triangular fragment into your tray.
Riverbank chores. Follow the planks to the riverside set. Plunder the black chest for tape, then snip a fishhook free from the taut fishing line using the scissors.
Reaching Branch. Fuse branch + fishhook + tape in the combine window until the recipe registers a Reaching Branch (long gaff). Use it on the suspended cage or pulley birdcage to fish down the blue triangle piece.
Breaker ballet. Return to the starting yard, unlock the fuse enclosure with the keyed hasp, and spin dials or throw levers until the schematic shows live bus. Note any color ticker or light strip that awakens beside the box—that order feeds the finale.
Triptych lock. Press red, then green, then blue wedges into the triangular wall pockets until they seat flush. The fresco wakes a chromatic keypad—no guesses until all three gems click.
Chromatic ladder. Tap color buttons in the exact order echoed next to the electrical gear (or on the newly lit diagram). When the sequence checks, a hidden ladder lowers into the pit, registering Riverside clear and cueing the next episode splash.
💡 Tips & Tricks
Photograph the Roman string the instant it glows—some builds extinguish UV art after you backtrack once.
If 3549 fails, confirm you did not read IV as six; under UV the I before V is easy to miss when smudged.
Route the poster maze with pauses between nodes; dragging through a wrong junction usually wipes progress on mobile.
Craft the Reaching Branch only after all three ingredients register; partial combines waste tape if the branch was never highlighted first.
⚠️ Common Mistakes
Entering 3459 or 3594 after mis-ordering IV and IX on the damp wall.
Solving the color panel before UV-revealing the poster, leaving the required pathway unknown.
Cutting the fishing line without the scissors hotspot armed, or forgetting tape so the gaff cannot assemble.
Random-mashing color buttons before the breaker animation exposes the canonical swatch order beside the cabinet.
