The Seamoth Perimeter Defense System is a defense-oriented Upgrade Module for the Seamoth. The module is crafted in the Vehicle Upgrade Console and must be applied to the Seamoth's upgrade panel to function.

Usage

The Seamoth Perimeter Defense System is used by left clicking after selecting the icon with one of the hotkeys (1-4). The hotkey used depends on where the module is placed in the upgrade panel.

  • Tap Left Click: The Seamoth will generate a small charge using 1 power (0.5%) from the Seamoth's Power Cell.
  • Hold Left Click: A large radius blast can be produced that uses up to 30 power (15%) from the Seamoth.

When using Ion Power Cells, a simple blast uses 0.1% of energy, while a fully charged blast uses 3%.

Killing aggressive fauna such as Stalkers and Sand Sharks is rather difficult without a large number of fully-charged blasts, which is highly costly on a Seamoth's energy reserves. Often, the better solution is to use a low-mid charge shock, which will stun predators and allow time to escape. Installing multiple Seamoth Perimeter Defense System modules allows blasts in quicker succession. Oftentimes only one module is required for efficient defence.

The Seamoth Perimeter Defense System does not affect the Ampeel, presumably because of the Ampeel's electrical nature. The Defense System can fend off Reaper Leviathans and Ghost Leviathans with only minimal damage to the hull. It is also a good defense against Warpers, as a charged shot is enough to cause them to temporarily warp away.
