1. The specific gameplay is first-person shooting. You can operate the protagonist to shoot, dodge, change bullets, throw grenades, etc., but there is no way to control the movement of the protagonist. Every time the protagonist moves, the system automatically switches.

2. Shooting in combat feels very good, shooting will have recoil, and some pressure gun operations are also required. In addition to using machine guns and pistols to fight at close range, some levels also need to use sniper rifles. At this time, you need to pay special attention to the order of sniping, and sometimes even need to snipe props first to attract the attention of the enemy.

3. Although the difficulty is similar every time you pass the level, there are also some random factors. For example, you will encounter random enemies who need melee combat. You need to click on the white circle that appears on the screen to win the melee combat, which tests the player’s ability to react and concentration.

4. You will get certain resources after each victory in a level. You can use these resources to buy equipment. Although the equipment can be upgraded, the upgrade is not only solved by in-app purchases. You must use the equipment a certain number of times to unlock the upgrade conditions.
