Zombie Siege.io

Construct impregnable defenses inside a tightly packed enclosure to repel the waves of brain-eating undead in the challenging base-defense strategy game Zombie Siege.io. At the beginning of each chapter, you get a couple of automatic firearms to deploy on a 3x3 grid. Some armaments, such as machine guns, occupy a single square, while airports, for example, require an empty 1x3 rectangle to deploy.

The objective is to use the space optimally, repel the zombie horde, and defeat the bosses in the final waves of each chapter. In between the levels, you’ll draw up to 3 different weapons. Identical weapons of the same tier can be merged to evolve them into a higher one, up to a cap of 5. Additionally, as you gain XP for killing the undead, you’ll select one of three skills to upgrade at each level-up.

How to play Zombie Siege.io

The sheer number of zombies might feel overwhelming at times. The keys to victory are to create a synergy among the defensive structures, choose optimal skill upgrades, and make the best of the new armaments you roll in between the waves.

Occasionally, you’ll get additional squares that can be used to expand your fortification. Proper placement of these tiles in relation to the shapes and sizes of your current military equipment is essential.
