Zombie Siege is an action-packed survival game where players control characters as soldiers defending their city from zombies while rescuing civilians who have fallen into zombie traps. The gameplay revolves around moving with left stick to dodge bullets and auto-fire when enemies get too close. The main objective of Zombie Siege involves building a team, using various weapons like the shield tank for defense against incoming waves of undead monsters (known as "zombies"), shooting at zombies from multiple angles while dodging their attacks.
The player must also use his/her medic skills to treat wounded survivors and maintain order in an otherwise chaotic battlefield. The game offers several unique features that make it fun: 1) Zombies: Zombie Siege introduces a new type of enemy, the zombie king (a large undead creature with sharp claws), which can be defeated by shooting at them from multiple angles.
