Quick answers

How many achievements does Terrible Lizards have?

15 on Steam and Xbox. Steam shows only “Welcome to Dalton’s Dinos” until you unlock the others; the other 14 are hidden.

What is the rarest achievement?

The collectible sets. Two days after launch only 0.1–0.3% of Steam players had Hoarder, Pterry’s Scrapbook, Bingo, Dino DNA, You Go Here or Audiophile.

Are any achievements missable?

We have not confirmed chapter replay, collectible carry-over or which achievements can be missed. Collect items as you go and keep track of the sets; do not assume NG+ will preserve your collection.

How long does 100% take?

The story is 6–10 hours according to the developers. We have not verified a 100% completion time or the total collectible counts.
