Enemies

Enemies are hostile entities in the game that try to attack your Tower. There are multiple different kinds of enemies that try to kill you.

In the game there are 3 categories of enemies: Normal, Elite and Boss.

Normal Enemies[edit | edit source]

Normal enemies include Basic, Fast, Range, Tank and Protector. These enemies are in a single group and their chance to spawn in a wave will add to 100% for each wave.

Protectors have special spawn rules with only 1 per wave and a cooldown between the next chance to spawn. There is a limit of 8 at once.

Basic[edit | edit source]

Basic Enemy

Your basic enemy, does nothing special

Common Enemy labs change the stats of basic enemies during rounds. When labs are researched, the base modifiers between enemies will no longer be accurate (ex: boss health will not always be x20 basic if basic health is researched).

Common Enemy Health Research[edit | edit source]

Lab Enemy Research Unlocks at Tier 9 wave 10 Milestone. Decreases basic enemy health at all waves. Has 30 levels.

Bosses in tier 1-6 will spawn at a fixed point during the boss wave. Tier 7 and above will randomly spawn the boss between 5% and 75% of the wave duration.
