Killer Sniper is an excellent shooter in which the player takes on the role of a ruthless sniper on a series of assassination missions. The game perfectly recreates scenes that can only be seen in movies, assassinating important targets, bodyguards constantly walking around to protect the assassination target, spotting gunshots and bodies to attract the attention of other characters, and much more. A realistic assassination scenario is recreated.

The game is played from a first-person perspective, giving the player an immersive experience. The sniper's scope can be switched between 2-12x at will, so players can easily target and achieve kills. During gameplay, players must take advantage of fleeting opportunities to make assassinations, as failure to do so will attract the attention of the target or others, resulting in the failure of the entire chapter. Of course, the player can also use the surrounding terrain environment to solve the target's mission. For example, there is a transformer box on the roof of a building and a puddle of water in the area next to it. If the box is knocked out of the plug, the water on the ground will be electrified. When the bodyguard passes by, he will be electrocuted; on the ground floor, there is a swimming pool on the right. When you kill the bodyguard next to the pool, he will sink to the bottom of the water so that he can remain hidden from the others for a while. All in all, each mission can be done in a different way, so use your brain to come up with the perfect way to do it.

As the game is a shooter, it involves changing the bullets for the guns and the player just has to swipe in the direction of the arrows on the screen.
