Primal Dread achievements and rewards

Primal Dread has 21 challenges: ten are “win a run with” one of the new characters, and eleven are tasks such as equipping five fossils or killing 100 raptors. Completing one unlocks a character, item or weapon in the game and the matching achievement on Steam, where the DLC’s achievements appear as their own set.

Bone Collector	Equip 5 fossils in a single run	Caveman	Nine fossils exist; Tooth is the cheapest. See fossils.

Trophy Hunter	Kill 20 different enemy types in the Jungle	Poacher	Counts Jungle kills only.
Crate Expectations	Pick up 10 crates in a single run	Survivor	Archaeologist digs up crates from four dig sites per wave. Players report it failing in co-op.

Achievement not unlocking

• Disable outdated mods. The developers warn that old mods can corrupt saves after an update, and players who could not unlock Survivor or Arsonist succeeded after removing mods.
• Use Verify Challenge Unlocks in the gameplay options to re-check completed challenges. The 12 November patch also fixed rewards that stayed locked on some saves.
• A save with “unlock all” content enabled does not earn achievements.
• Look for DLC achievements under Brotato: Primal Dread on Steam, not in the base game’s list.
