How to deactivate a tower

XANA can activate a tower on Lyoko during periods of activity or when you try to destroy a replica to attack in the real world. The only way to stop the virus's offensive is for Aelita to get to the activated tower and enter the Lyoko code. See the tutorial 'Monitor the progress of a XANA attack' to estimate the time remaining to disable the tower. Some attacks can be slowed down, see the tutorial 'Slow down an attack with the network controller'.

Step 1: Find the activated tower

First, you need to find the location of the tower activated by XANA.

Initialize the Metascan or SuperScan program. The program normally automatically targets the activated tower. If necessary, you can also search manually for the activated tower using the commands monoscan.xana or superscan.xana.
Important:
If the Metascan does not find anything, it means that the activated tower is in the 5th Territory. To be able to analyze the tower, you need to be connected to that territory.
```
monoscan
superscan
```
Click on the blue circle in the top left corner of the SuperScan to find the activated tower in the 'Virtual Map'.

Aelita must then go to the activated tower in order to enter the Lyoko code and thus stop XANA's attack.

If the tower is on Lyoko, virtualize Aelita as well as the other Lyoko warriors to a tower near the one activated by XANA. See the tutorial 'Virtualization' to learn more about this process.
Ask the Lyoko warriors to get to the activated tower from the 'Locations' tab in their 'Com. Card'.
Fight the monsters guarding the tower while protecting Aelita. See the tutorial 'Fight on a virtual world' for more information on battles.

Have Aelita enter the tower with the 'Enter Tower' option in her 'Actions' tab 'Com. Map'.
Have Aelita climb the tower with the 'Climb Tower' option.
Deactivate the tower with the 'Lyoko Code' option. This immediately stops XANA's offensive, except for the meteorite attack.

If the activated tower is on Lyoko, you absolutely need to execute a Return to the past to repair the damage caused by the attack.
