2. Story plot: The game as a whole tells the story of how the protagonist Jack searches for his wife in a biochemical disaster. I personally feel that the entire story mode is like watching a Hollywood thrilling horror blockbuster. The overall story is very compact and interlocking, and there are no parts that make me feel superfluous. The tension and relaxation of the story are also well matched. But there is still a certain regret that he is not perfect, and this is what troubles me the most, because the protagonist Jack's wife died in the end. However, there is such a thing as imperfection, and maybe tragedy can touch people's hearts. Maybe you can create another ending. So I rated it 9.9 points! 
System Weapons: The weapons in the game can be said to be very rich, including knives, pistols, shotguns (which are what we often call violent guns in CS), light machine guns, heavy machine guns, and rocket launchers. It is said that there are more than 20 in total, but I have not collected them all, which is a pity. Different weapons have different characteristics. My most recommended ones are shotguns and heavy machine guns. Although the rocket launcher is quite powerful and has a large damage range, I personally always feel that it is a bit awkward to use, so I have to settle for third place. Various firearms can also be modified. For example, some weapons with poor stability can be improved a lot after being modified. Exploration and puzzle solving: There are many places to explore in the game. You can rummage through various cabinets, boxes and other places. Sometimes it will be a surprise to discover drugs that increase the upper limit of life! But I think some of them are still hidden too deeply, such as a hero medal in the police headquarters. If you don't know it in advance, you really can't find it.Overall, the game still lacks puzzle-solving elements. It would be perfect if it could be deepened in this aspect. QTE: To be honest, this is also the first time I have seen a QTE system in a mobile game. In one word, cool! After reaching certain conditions in the battle, you can QTE the BOSS. Only when the QTE is successful can the BOSS be truly killed. However, sometimes it is a bit dangerous to encounter several monsters that require QTE at the same time, and you must defeat them one by one. Challenge: In fact, I am not suitable to evaluate this aspect, because most of the challenges I still maintain at around 2 stars. To put it simply, the challenge is to let me kill all the attacking monsters. It seems simple but it is actually very difficult, and from my feeling, the difficulty will increase accordingly with each additional star. Mode: In addition to the ordinary story mode, the game also has an infinite mode and a survival mode. The infinite mode has unlimited bullets. I haven't turned it on yet. You need to collect 12 hero medals in the story mode to open it. The survival mode can be turned on as long as you clear the level. In this mode, monsters are constantly attacking, and the weapons are limited at the beginning, only a poor knife and a pistol. After that, the number of weapons will slowly increase. It is quite a test of our player's operation. I didn't understand it very well at first, and I was bitten to death by zombies all of a sudden. So I rated it 9.6 points! 
Operation The overall operation of the game is quite convenient. I am playing the touch screen version, which has virtual buttons. It is very convenient to press to move, attack, investigate, change guns, open and close the mini map, and take medicine. So I rate it 9 points. This game by Jing Zhongyue has been greatly improved compared to previous games. It can be said to be one of the best among mobile games. The content of the game is quite generous and you can feel the developer's intentions. Just before I finished writing this review, I heard that Jing Zhongyue has started planning the second generation. I hope that Jing Zhongyue can see what I said and that there are more fun elements in the second generation. I have begun to look forward to the second generation and hope to play it as soon as possible! Haha, I've written so much without realizing it, and there's a lot more I want to say, but I'll stop here. It would be bad to spoil too much, so you'd better experience it for yourself!
