Use this page as a status checkpoint before spending a run chasing an unverified currency route. The current Roblox description confirms Michael's Zombies 2.1.0, ammo attachments, hidden stashes, PHD Crashout and Hallows Eve's return, but it does not publish an Emerald economy, attachment-shop price table or guaranteed farming method.
Recent community demand makes the topic worth covering: a Reddit player asked whether Emeralds can be earned by playing or only bought, while community wiki/search surfaces frame the Ordering Menu and attachment pages as the relevant shop vocabulary. Those are useful source-watch leads, not official mechanics. They explain why this page exists, but they do not authorize a fake recipe.
If the live game shows an Ordering Menu, UV light prompt, Emerald balance, event reward or shop option, treat that screen as stronger than a stale guide. Until a creator-linked source or repeatable live packet confirms the full flow, this page links users back to Attachments, Hallows Eve and Sources instead of publishing exact prices, odds or rewards.
