Subnautica Below Zero
Subnautica Below Zero

Subnautica’s Below Zero world is submerged, so the mode of transportation is also related to water. When you only start with a suit, you can unlock several types of suits and sea trucks. There are also multiple upgrades for each marine suit and truck. Peripheral defense is one of Subnautica’s Below Zero country’s Sea truck upgrades.

Perimeter Defense Upgrade can generate electric fields around Seatruck to frighten predators. In this guide, you will learn where to find in Subnautica below zero and how to use perimeter defense upgrades.

Perimeter defenses will generate electrical charges around the sea truck to repel Leviathan and other marine life. To use perimeter defense, all you have to do is hover your mouse in the upgrade slot and click the left mouse button. This will send the charge around the sea truck and shock away from leviathans and other creatures. Holding the left button for a few seconds will increase the collision radius.

Perimeter defenses consumes some of the power of the sea truck. In fact, larger explosions consume a lot of energy, consuming 7.5% at a time. The impact may not kill the creature, but it will reduce the damage to your sea truck and reduce the time to repair it.

This is one of the most powerful sea truck upgrades you can get in the game. It is only available in one location, in addition, that location can only be unlocked in the second half of the game. You can only find perimeter defenses at the Maraguerit Maida’s base.

Players can unlock the base only after disabling Marguerit’s communication tower. After deactivating the communication tower, meet Margaret in her greenhouse and get the information she promised. After visiting the greenhouse, the base will be unlocked.
