"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.

Kind of familiar

I enjoy playing the game as i have been playing the other games of yours named Epic seven for more than 10 years already. Love everything of it, but it reminds me the feeling of playing Genshin Impact when it comes with partner parts, the crystals and how you visualise the summoning. Oh and with the membership benefits as well, all just kind similar. This is my opinion. Great works overall

Great Game just needs a little tune

Having a lot of fun so far, the fighting mechanics and strategies are intriguing and allows me to be creative with how I approach every fight, the only issue i’m having at the moment is after finishing a battle the screen will just sometimes freeze and I can’t do anything but reload the game which gets a little annoying but other than that goated

Honestly the graphics were so good i thought the animators should make an anime, absolutely amazed. The game is smooth, the plot is intriguing and the characters all look great! The system of the game is well planned and the voice actors are amazing(as well credited!) loving the game so far, and had to write a review (they dont ask for one)

Solid but Greedy

The game is overall quite good. Fun gameplay and graphics. However, it uses the Hoyoverse pricing model without having the same level of quality. The story is lacking in depth and quality, and isn’t fully dubbed and none of it’s dubbed in English, and there are mistranslations in the text. If you’re going to ask for that money at least make the product at the same level as the competition.
