Disclosure, Sources & Methodology

Unofficial fan site

Where the data comes from

• Item names & rarities are transcribed from a community item guide on the Steam Community and supplemented with Steam news for later events and DLC. We do not claim an independent per-item verification trail.
• Drop rates are community-reported per-rarity figures (Common 90%, Uncommon 9.5%, Rare 0.49%, Epic 0.01%, Legendary ~1 in 500,000). The developer has not published official rates, so we keep the community values as-is — they sum to ≈100.0002% due to rounding.
• Achievement unlock % come from the public Steam global achievement API. The display names and conditions are inferred from the internal keys and labelled as such.

What “verified” vs “inferred” means here

We treat item names/rarities and achievement percentages as sourced facts, and we flag anything derived (achievement conditions, DLC hat names still to be confirmed) as inferred or unverified. Limited event and DLC items appear as index rows rather than full detail pages until their fields are fully confirmed — we do not present unverified data as fact.

Tools & honesty

• The rarity calculator gives per-rarity expectations only — never a single-item probability.
• Chest cadence is an adjustable input because the official rate is unpublished.
• An inventory-value estimator is planned but gated on Steam Market terms and mapping; it is not live.
