Echocalypse Guide Hub — Official Facts, Codes & Character Rankings

Home / Echocalypse

Echocalypse: The Scarlet Covenant is a post-apocalyptic strategy RPG published by Yoozoo (Singapore) Pte. Ltd for mobile and PC. It has no public first-party stats API the way a Roblox game does, so this page works from what the official storefront listings themselves state rather than a live counter. At the August 18, 2026 reading, the Apple App Store listing showed the app last updated May 18 at version 4.6.5.

Coverage stance: We have dated facts read directly from the game's own Steam, App Store and launch-announcement listings, and we have not played Echocalypse. There is no live player count to quote for a non-Roblox title without a public stats endpoint, so we are not inventing one. This hub stops where the storefronts stop — no strategy guide, no invented mechanics. Our codes page goes further and shows, in the open, why most of the short codes circulating for this game do not survive being checked against each other.

Background

Sources disagree on when to date Echocalypse's launch, and we show that disagreement rather than pick one. A QooApp news article published October 11, 2022 reported a global mobile launch of October 20, 2022, crediting Yoozoo Games, a Shanghai-based studio. The Steam page, read August 18, 2026, lists a separate June 7, 2024 release date for that platform and names the publisher as Yoozoo (Singapore) Pte. Ltd. The App Store's own "What's New" text, still showing as of our reading, announces a "2.5 Year Anniversary going live on May 16" with a new playable character, Honorblade Chiraha, in her Oath Outfit "Gentle Drink" — a span that does not line up cleanly with either launch date above. We state what each source says rather than reconcile them into a history we cannot verify.

How the Game Works

The Steam page, read August 18, 2026, describes Echocalypse as a card-battle RPG built around collecting characters it calls "Kemono girls," with skip and auto-battle functions, one-click character levelling, and separate modes for expeditions, an arena, boss battles, dormitory customisation and guild activities. The App Store listing separately names an "Oath System" for character relationships and a mode called "Witch's Den." Both listings state the game requires a third-party GTArcade account and carry content warnings for suggestive dialogue, animated blood and partial nudity. That is the extent of what the storefronts describe. We have not played Echocalypse and will not characterise combat pacing or which modes are worth a new player's time from second-hand summaries.

Codes

Echocalypse does hand out codes, but the lists circulating for this game are inconsistent, and the codes page linked below is deliberately short as a result. Rewards are paid in currencies including Iridimorphite, Tribute Points and Echo Crystal Flakes. Codes are entered from the character profile icon, through Basic Data settings, using the "Redeem Code" field — full detail, sources and caveats are on the codes page.

Update Rule

We do not mark a code as active just because another page says it is active, and we do not state a fact about this game unless a dated listing we opened says it. This page records what was checked, when it was checked, and where the evidence runs out.
