Nailed It — Nail down 100 objects
A crew-style checklist task: connect 100 objects to surfaces using the Nailgun.
Requirement
Nail down 100 objects using a Nailgun. Any 100 objects stay on the counter of deeds, not one run — the requirement does not state a cutoff, and the platform text does not say whether the count carries across sessions.
Fastest route (community-verified)
A published TrueAchievements guide (Sep 23, 2026) reports that the grind can be done in the HQ without starting a Job: load into the HQ, fire the Nailgun at every loose object you can find, and when you run out of nailable props, return to the main menu and load the HQ again. After 100 nailed objects the certification pops. Read the same page in the HQ guide.
Playing normally
You also earn lots of progress passively: every path you build during Jobs adds to the count. On a standard playthrough the certification usually unlocks before or while clearing the third Job — 100 nails is a few bridges.
Unverified details
- Whether the internal counter persists across sessions — platform text silent; HQ-loop method works either way.
- Whether nails count when they break instantly on physics objects — no test data published.

Nail 100 objects with the Nailgun. The fastest documented route is nailing every loose object in the HQ and reloading to reset the scene.
Does the HQ count for Nailed It?

Does the counter carry over between sessions?
Not stated in official or platform data either way; the community method does not depend on it.
