The Arrestor Beam is the ship counterpart of the Arrestor Beam Turret, once popular amongst players due to its ability to slow down an enemy fleet's advance.

It fires a translucent red beam at its target and maintains the beam for a prolonged period of time. It doesn't do much damage but impedes the target's movement according to the stasis amount.

Strategy and Setup


Arrestor Beams cannot be dodged: once a ship is fired upon, it is slowed long enough for the rest of your fleet to catch up and decimate it. Focused Optics allow your ships to slow down enemies from afar, preventing their escape. Beam Capacitors can additionally shorten the charge time of this weapon.

Arrestor Beams can also be used to prevent the enemy from shield-switching, or to exploit their blind spots.

This weapon is best used on short-range ships: its stasis ability allows your ships to close in and gain an advantage in close combat.


Arrestor Beams deal almost no damage but take up a lot of mass, meaning that using this weapon will significantly decrease your damage potential.

Arrestor Beams have a long charge time and hence ill-suited for kiting, since enemies will get in range to fire long before you could slow them down.


  • The Arrestor Beam used to have 3,000 m range, 2s charge time, 6s beam duration and 1s cooldown time. The weapon got severely nerfed due to their overuse on battleships, and is now a catch-and-kill weapon rather than a kiting weapon.
  • The Arrestor Beam has the lowest DPS of any weapon in the game, even lower than the Pulse Ray I.
