Sneaking in the dark without anyone see us. Observing its target, and approaching it in silence. Choosing the weapon and jumping at the right time to execute it. All these actions are part of the daily life of a killer. He must execute people in exchange for a reward. The latter is often cash, delivered in a suitcase.
In the killer games, you have to take on the role of an assassin and to kill your victims without alerting security or other persons who may be nearby. Act quickly.
