Players can unlock achievement by collecting all Arch artifacts in Stalker 2

Players can unlock the "Curiouser and Curiouser!" achievement in Stalker 2: Heart of Chornobyl by collecting all six Arch artifacts located in various anomalous zones. These artifacts provide significant benefits without radiation side effects but come with debuffs. The Arch artifacts include the Weird Ball, which reduces bullet damage but increases weight with each hit; the Weird Flower, which enhances stealth but requires rest to recharge; and the Weird Water, which boosts weight capacity but causes alcohol-like symptoms. Other artifacts are the Weird Bolt, which lowers damage from anomalies but needs charging during emissions; the Weird Pot, which alleviates hunger but inflicts PSI damage; and the Weird Nut, which helps with bleeding but slows healing. Collecting all six artifacts grants players the achievement worth 20 points.
