Monsters have invaded the city, and only you can protect it!

- Grab your gun. Don't forget the special luminous ammo against the monsters.
- Hide in the shadows. Use the element of surprise to deal maximum damage to monsters.
- Use the walls as cover. Monsters won't get you behind them.
- Shoot accurately. Aim for the head, that's exactly what they don't like.
- Hunt bosses. After defeating them, the rest of the monsters will scatter.

Prove that you are a professional in your business!
