Mech Assemble: Zombie Swarm is a roguelike bullet hell game with gacha elements, where players collect and upgrade powerful mechs to survive against waves of relentless zombies.
Choosing the right mech is crucial for progressing in the game, as some mechs excel in crowd control while others are better for boss fights or specific scenarios.
This tier list will help you decide which mechs are worth investing in to maximize your performance, especially in the late game where challenges become more intense.
What is Mech Assemble: Zombie Swarm?
Mech Assemble: Zombie Swarm is a fast-paced, roguelike bullet hell game where players control mechs equipped with unique abilities. The core gameplay revolves around assembling a squad of mechs, each with its own special attacks and passives, to battle hordes of zombies across procedurally generated stages.
What makes the game unique is its blend of gacha mechanics and roguelike survival, requiring players to collect mechs through random draws while also mastering bullet-dodging combat. Each run challenges you to survive as long as possible, collect upgrades, and adapt to increasingly difficult waves of enemies.
The game’s depth comes from the variety of mechs available—some specialize in raw damage, others in crowd control, while a few excel in utility or tanking. Building the right team is essential for surviving the toughest stages, making a reliable tier list a must-have guide for players.
