What the platform listings confirm
The Steam product lists Steam achievements as a feature. The Xbox product separately lists Xbox achievement support. Those are official product disclosures about the sequel, not a copied list from the original Boltgun.
The Steam overview and Xbox store overview identify the verified products. Feature support is the specific answer supported by those listings. It does not establish that platform achievement counts or unlock conditions are identical.
Why there is no retained complete list
The research did not obtain a complete list that could be cross-verified against an official platform disclosure. Search results and a reported list lead were insufficient to establish final unlock instructions. No achievement title or number from those unverified leads is included here.
The initial Boltgun has its own achievement and expansion material. That older inventory does not establish the sequel’s list. This page therefore retains the product feature rather than offering a falsely complete roadmap.
Difficulty and accessibility requirements
The difficulty guide documents reported demo presets and announced accessibility options. Those sources do not establish how a particular toggle affects an achievement. No eligibility rule is inferred from the presence of Invulnerability or Unlock all weapons.
Likewise, the dossier establishes no verified missable or collectible achievement requirement. The collectibles page confirms purity seals without assigning a reward or trophy. Platform support and completed unlock testing remain separate claims.
The current completion answer
The available evidence is enough to confirm support, but not to plan a guaranteed completion run. It does not supply a verified Gamerscore total or PS5 Platinum count. A full roadmap must be based on the actual final list and reproduced requirements rather than launch-trailer footage.
