Chapter 4 Challenge 5: Officially Confirmed Hard

IllFonic itself names this stalk-Bob-and-Lynda objective as one of the four hardest story challenges. Here’s what’s officially confirmed — no invented steps.

THE SHORT ANSWER

The objective is to fully build Stalk on Bob and Lynda together in the living room before their scripted scene. IllFonic’s September 17, 2026 roadmap post names this as one of four story challenges giving players the most trouble sitewide, and says the team is evaluating adjustments to make it easier.

What’s officially confirmed

IllFonic — What’s Coming Next ↗ names Chapter 4 Challenge 5 — fully stalking Bob and Lynda together in the living room — as one of four story challenges that IllFonic itself says is “giving players the most trouble,” alongside Chapter 2 Challenge 6, Chapter 4 Challenge 6, and Chapter 5 Challenge 6. IllFonic states the team is looking at adjustments to make it easier, without giving a timeline beyond the general patch schedule on the roadmap page.

Why this page doesn’t have a step-by-step route

We don’t have a verified, sourced walkthrough for the specific positioning and timing this stalk objective requires, and Ya (who maintains this site) hasn’t played the game to test one. Rather than invent steps that might be wrong, this page sticks to what IllFonic has confirmed: the objective exists, it’s officially acknowledged as unusually difficult, and it’s connected to the broader Chapter 4 sequence covered on the Chapter 4 challenges page.

If it won’t register even when you think you completed it

Chapter 4’s scripted Annie/Bob/Lynda/Laurie sequence means killing targets out of order can lock other objectives for that run — see the full sequence notes on the Chapter 4 page before retrying. If the stalk condition itself seems met but the challenge doesn’t clear, that’s a tracking question — check Challenges not counting rather than assuming you missed a hidden step.
