Call of Duty: Zombie Shooter

This is a simple game where you play as a soldier shooting zombies. The goal is to survive as long as possible and get the highest score. Use the arrow keys to move and the space bar to shoot. Zombies will randomly spawn from the top of the screen and move down. Shoot them before they reach the bottom or they will damage your health. If you get hit too many times, it’s game over. The game is designed to be playable on smartphones, so it has a simple interface and uses emojis for buttons.
