[h1]Drone

Price: 2,000 cr.

Dimensions: 4x1 m.

Cargo capacity: 0 crates.

Recommended crew size: 1

Recommended crew experience: Experienced[/h1]

In the water column or among the rusty ruins, her presence is barely noticeable, like another inhabitant of the depths.

She will guide you through the labyrinths of the caves, illuminating your path. She will break through the ice blocks, clearing a path, and share her oxygen and inventory space with you. In a critical situation, she will rush towards the threat to distract the enemy, or carry you away on her back.

She is our invisible guardian, our deep-sea explorer, who allows us to see and act where we would not dare to go ourselves.

Armament:

  • Pulsed laser [1 pc.]
  • Launcher [1 pc.]

Characteristics:

  • Speed: 57 km/h
  • Ascent speed: 19 km/h
  • Diving speed: 22 km/h
  • Engine power 1: 2
  • Engine power 2: 2
  • Battery capacity: 600 [~22 pulse laser shots]

Features:

  • The drone has two modes: combat mode (red lights) and movement mode (green lights), which are switched by quickly double-clicking the left mouse button.
  • To detach the drone, you need to use the drone control periscope on the captain's bridge, which is located to the left of the navigation terminal. Then, hold down the left mouse button and point in any direction. As long as you hold down the button, the drone will move towards your cursor.
  • Medium equipment rack.
  • Oxygen tank replenishment cabinet (stops working if you use up all the energy by firing a pulse laser).
  • An evacuation module made from a boarding capsule in a depth charge charger (holds 1 crew member) (can also be used for firing depth charges).

All submarines in the «Black Rock» collection from level 1 to 3 have this drone on board. This work includes the drone itself for modification and a drone file labeled as DEV KIT, which includes all the elements for installing the drone on any other submarine and detailed instructions for all components.

Mods that can cause problems with drone operation:

«Performance Enhancement» - Balanced и Compatibility preset work fine, but Performance and Extreme Performance do not allow the drone to detach from the sub.

«Item Optimizer» - Do not let the drone detach from the sub.

[h3]Other features:[/h3](The location and appearance may vary, as some of the examples are universal for the «Black Rock» series.)

⸻ All signs and buttons in the interfaces on the entire submarine have been translated. The translation changes automatically depending on the language you are using.
