"Chaos," a black fog that consumes planets, distorting their environment and lifeforms. The beginning, or the end, of every story. [The Blue Pot], a Chaos located on Earth, the birthplace of humanity. There have been reports of unidentifiable creatures being discovered.

Super F2P Friendly — Great Launch Rewards

This game has to be one of the most F2P Gacha games made, I started less than a week ago and I already have 6 5-Star units, while one of them is E2 (Renoa <3), while majority of my 4-Stars are close to reaching E6. It’s a very fun experience overall, the gameplay, story, and runs are great. Some translation errors tho as it does cause some confusion but devs are very proactive and compensation for maintenance is quite generous. Start early for a whopping 50 pulls (10 pulls for free every week), and a maintenance compensation of 30 standard pulls and 1700 currency. Love the game, keep up the great work devs 💝

This might be the first time I’m going to write a review for the best game of the year 2025. WOW, to the developers! I never had a game like this, I can’t find the words to describe the level of euphoria. AMAZINGLY done, although learning it takes time. The JOY of playing this even after errors OMG the best of the best. It’s unpredictable and very adventurous. I hope more protos ( players) find this gem. Please advertise your game it deserves the hype. WELL COOKED!

nah actually tho, this game is sooooo good, the mechanics are so interesting, there’s so much to do, the story is good, and there are so many different builds and character synergies, and what i love most is the 5 star characters dont outshine the 4 stars, some 4 stars are as good or even better than the 5 stars with the right build and team comp. this game is sooooo fun, please keep doing what yall are doing.

The game was doing perfectly fine before and I had no issues as I played until after the new story update. Somehow, the game is still trying reconnect even tho I had strong signal and its just this game. Arknights, Limbus and even NTE were fine with it but CZN? I couldn’t even get pass the loading screen without reconnecting issues. ITS EVEN WORSE AS I PLAYED! Each card played would make it try to reconnect again and again until I had restart the app. Please fix this issue, I had so much fun playing this game until this issue started to show up.
