In Stick Killer, you can earn money by completing missions, eliminating targets, and surviving longer periods within the dangerous city environment.

The main dangers include aggressive pedestrians who do not avoid vehicles, and the police who use live ammunition, making it very challenging to survive.

To avoid the police, you can use various strategies such as blending into crowds, using cover effectively, or finding alternative routes that are less patrolled.

Yes, you can upgrade your character's abilities and equipment using the money you earn, which helps improve your chances of survival and success in missions.

Stick Killer features multiple levels and areas within the city, each with its own unique challenges and environments, providing varied gameplay experiences.

If you get caught by the police, your mission will likely fail, and you may lose some of your accumulated money or even restart from an earlier checkpoint.

Stick Killer does not feature a multiplayer mode; it is designed as a single-player experience where you navigate the dangerous city alone.

The game ends when you successfully complete all the objectives or when your character is killed without completing the mission, depending on how far you progress in the story.
