In Toilet Tower Defence Items, the choice of units directly determines whether the player can successfully defend against the enemy's attack. The U4GM website provides a comprehensive unit classification guide to help players choose the most suitable units according to different needs. The units in the game are mainly divided into offensive, defensive, auxiliary and special types. Each unit has its own unique functions and roles. Understanding their strengths and weaknesses is essential to developing an effective strategy.

Offensive units are one of the most common units in the game and are specifically used to eliminate enemies. Units like "Super Toilet Blaster" have high-range attacks and can quickly clear a large number of enemies, making them suitable for dealing with groups of enemies. The advantage of offensive units is their strong output ability, but the disadvantage is that they usually lack defense and are easily defeated by the enemy's powerful attacks. Therefore, it is the key to win to arrange the placement of offensive units and cooperate with other types of units.

Defensive units are designed to resist enemy attacks and usually have high health and deceleration effects. For example, "Steel Wall Toilet" can slow down the enemy's progress and provide a solid line of defense. The role of defensive units is not only to attract enemy attacks, but also to buy more time for offensive units in the rear.

Although auxiliary units do not have direct attack power in the game, their buffs can significantly improve the combat capabilities of other units. "Magic Toilet Brush" is a typical auxiliary unit, which can increase the attack speed of surrounding units, thereby enhancing overall output.

Special units are the most unique units and usually play a huge role in specific situations. For example, "Plunger of Doom" can cause a lot of damage and is suitable for dealing with high-health enemies.

The unit classification analysis on the U4GM website can help players adjust the lineup according to the battle situation to ensure that each unit can maximize its role.
