Tidal Defense Simulator in Wuthering Waves, explained

The latest update of 2.6 will offer several events for players to partake in, with the Tidal Defense Simulator being the highlight. As mentioned previously, it is a simple Tower Defense mode where your objective is to stop hordes of enemies from reaching a particular point of the map. Once enough foes reach the target, its HP will be dropped to 0, and you will fail the stage.

The event is live as of August 30, 2025, and will end on October 8, 2025, in the concluding days of version 2.6.

To combat these enemies, you will be given access to several contraptions. You cannot use your Resonators here and will have to rely on your ability to strategically place the traps to overcome each stage. Let's take a look at everything you need to know about the event.

The map and Matrix

Each stage of the Tidal Defense Simulator event in Wuthering Waves will have different maps. When you open them, you will be able to find several icons. The red ones will be the spawn room for the enemies, while the blue one is the Matrix that you will need to protect.

The Energy Matrix can be destroyed once a certain number of enemies reach it, so it is up to you to set up defenses accordingly. Keep in mind that there can be multiple enemy spawn rooms for a stage, so you should invest your resources accordingly.

Sim Credits and traps

Similar to any Tower Defense mode, you will start each stage with a currency called Sim Credits. This is what you will use to purchase the traps to set up throughout the map. Completing a wave will give you Sim Credits based on your performance.
