The gameplay of version 3 is very different from previous versions. The game developers have divided the gameplay into 3 stages: view, search and run. In fact, in this game, you must first thoroughly examine the environment and find out the locations of the enemies and their movements, and then find the best way to reach the goal and complete your mission. But the need for these changes is to increase the artificial intelligence of the enemies so that they can move freely in the environment and do different things, instead of always doing a certain thing and going a certain way. To make things difficult for the player and force him to think. The creators have stated that artificial intelligence has been greatly improved in this version, and in addition to the sense of sight, soldiers also have a sense of hearing, and as the sound of footsteps approaches, they become suspicious and search for you in the environment. To prevent your presence in the environment from being revealed, you should always move in the dark and in the shadows and avoid the enemy's field of vision so that you can perform the steps. With the increase in the AI ​​of the enemies, the high value of the expansion of the environment becomes apparent. The wide environment of this version gives you the ability to use different ways with proper and easy planning so that you are not recognized by the enemy, but if without planning. Let the environment be sure that your death will be certain, so the importance of planning and using tactics in this version will be very high.
