Tower Defense Simulator Swarmer rework explored

Swarmer in Tower Defense Simulator was an old tower that was removed from the game in 2020.

Its functionalities received a complete overhaul, removing any unintended effects and boosting its combat efficacy.

Here’s everything you need to know about the Swarmer rework in Tower Defense Simulator.

An overview of the Swarmer rework in Tower Defense Simulator

Tower Defense Simulator's Swarmer received a complete rework with the version update 1.63.0, which was entirely dedicated to the tower. Its basic functionality has been given an overhaul, which allows it to deal damage with its main attack. Additionally, instead of spreading its debuffs out, it will prioritize a single target that you choose.

The rework allows multiple Swarmer units to interact with each other, leaving room for effect stacks. You can have up to 5,000 cumulative Swarmer debuff stacks, with each unit having a maximum individual stack limit of 150. The active stacks can be viewed under the enemy’s HP pool.

Unintended effects, like the tower waiting for enemies to enter its range, have been addressed. With the ability Bee Swarm Grenade, the unit will immediately chuck the grenade out when available instead of waiting for the targeted enemy.

Additionally, only one stinging time from an effect is active at once for any specific enemy. This prevents effect stacks from resetting each time a new stack is applied. The bug also made it so that the shortest effect duration would determine the length of all active effect stacks, ending many of them prematurely.

Lastly, the Sting damage applied by the bees has received a visual change, displaying regular damage indicators instead of the poison version.
