Description

edit

The Toxicity Trouble Event is an event in Tower Defense Simulator. It brought one new tower.

The event started on July 29th, 2025 at 3:00 EST and ended on July 29th, 2026 at 3:00 EST.

Cash is only gained if an enemy is killed, or in some cases, damaged by a specific amount of health. Additionally, the amount gained is a set amount of cash, which is not always equal to the enemy's health. It uses a slightly different method of distributing cash between players, as enemies split their cash between players, regardless of how much damage the player dealt to it. If, in a duo, one player does all the damage to an enemy, both players will receive 50% of the cash the enemy would normally give in solo. This means that in solo, you receive 100% of the cash when an enemy is killed, or it is damaged enough. With each additional player, this is reduced to 50% in duo, 33% in trio and 25% in quad. If it is a decimal, it gets rounded up or down depending on the decimal value. If it is at least 0.5, it gets rounded up. If it is less than 0.5, it gets rounded down. For example, the Hidden Boss gives Cash$600 when killed in solo, Cash$300 in duo, Cash$200 in trio and Cash$150 in quad between the players that damaged it.

Enemies increase their health by 20% with each wave due to the Mutation modifier. The base health is also set to 300, regardless of the players' levels, due to the HP Locked modifier.

Story

edit

Story: Dispatcher gets informed of an acid wasteland gaining dangerously high levels of mutations, so Dispatcher sends Brawler, Scout, Commander, Accelerator, and Minigunner to go figure out what the issue is. Shortly after arriving, Dispatcher alerts the team of a new recruit by the name of Toxinator. A loud growl is heard from the entrance and Dispatcher tells the team to get ready. Commander chooses to sit from the sidelines and command the team.

Wave 20: Upon reaching wave 20, Slimed Down Acid, Armored Acid, Acidic Sorceress, and Intoxicated Skeleton rise up from the ground and rush to the T.D.S. Organization's base, ready for revenge.

Triumph: Upon defeating the Acid Obliterator, Toxinator starts leaving when Commander stops him and asks if he'd like to join. Toxinator agrees after a few moments and the team walks back to base. The camera pans to an Acidic Sorceress who smashes a potion onto the ground as the screen cuts black.
