Thriller Battlefield was a very popular mobile game, but it had some shortcomings, including the following aspects: 1. Difficulty of operation. The exciting battlefield required players to have good reaction speed and hand-eye coordination to be able to deal with various situations in an emergency. For new players, this game might take a longer time to learn and adapt. 2. The quality of the game's graphics and sound effects was not high enough. Although the images and sound effects that stimulated the battlefield had been optimized, there might still be some flaws or imperfection. Especially in terms of image quality, some scenes might be blurred or distorted. 3. The social functions are not perfect. Although Thriller Battlefield was a multiplayer game, its social functions were relatively weak. Players could not communicate via voice or send messages, which might limit the interaction and communication between players. 4. The game content was not updated frequently enough. Although the game had been online for many years, its content and updates were relatively infrequent. Some players might find the game too monotonous and boring. As an excellent mobile game, although there were some shortcomings in terms of operation difficulty, picture quality, and social functions, these shortcomings could also encourage game developers to pay more attention to the needs and feedback of players and constantly improve and improve the game.
