Kronos vs Prima Games eGuides

Kronos is a companion app for Call of Duty Zombies players, providing Easter Egg guides, interactive maps and in-app tools. Guides divide Easter Eggs into steps with screenshots, and players can check off objectives to track progress. The homepage says coverage spans more than 40 maps, from Nacht der Untoten to Shattered Veil. A Memorizer tool tracks Simon Says color and number sequences and includes a one-tap reset. Players can vote on the next CoD Revival and view a countdown and community vote results. Kronos works offline and syncs offline; its free plan requires no signup. For phone sign-in, it stores a phone number and Firebase user ID to sync progress, bookmarks and guide history across devices. Its privacy policy says Firestore access is restricted to the authenticated account and users can delete their account in app settings. Kronos is available on Android, iOS and web. The privacy policy also lists Firebase Authentication, Cloud Firestore, Analytics, Crashlytics and Cloud Messaging.

Prima Games eGuides is a web library of official video-game strategy guides. The archive lists 251 guides and 25,589,130 words of strategy, while a redeem-code page says 256 guides are available in full with a free account. Guides include walkthroughs, maps, collectible checklists, and boss tactics, with full-text search across the collection. Without an account, readers can finish three guides and open the first three sections of other guides; a free account opens every guide in full. Guides work on phones, and checklists remember where a reader stopped. Maps and checklists load inside guide pages from cartographer.gamurs.group, so privacy extensions or networks blocking embedded frames can prevent them from appearing. The store is closed, meaning guides cannot be bought or refunded through the site. Old accounts, owned guides, and purchases were migrated, and sign-in can use an old email or a one-time link expiring after 15 minutes. Available guides were published from 2009 through 2018.
