The Epsilon ECHO Cannon is a powerful Energy weapon with the ability to bounce across nearby targets, dealing extra damage.

It fires three thin yellow pellets before reloading.

The Xeno Epsilon ECHO Cannon is an advanced version of the Epsilon ECHO Cannon that has built-in range increase and deals Alien Damage, taking on a green coloration.

Strategy and Setup


Epsilon ECHO Cannons build on the strengths of the ECHO Ray, being able to effortlessly damage the entire enemy fleet at once with the insane chain count. They can also destroy many squadrons at once and potentially ricochet towards the enemy carrier from extreme range.

Epsilon ECHO Cannons perform best when also equipped with range extenders such as Beam Capacitors. The intrinsic range increase of the Bastion Cruiser can further stack with this bonus, enabling this weapon to achieve a whopping 5,200 m even without its Overdrive effect.

The Xeno version has extra range that substitutes the Beam Capacitor, freeing up a special slot for other uses. Xeno Beam Capacitor is still useful for clearing out squadrons.


Like other chain weapons, Epsilon ECHO Cannons are ineffective against a single target; even Pulse Cannons exceed their mass efficiency. As a result, it becomes difficult to focus down one target at a time. Counter Chain technology such as Spectral Shells render them much less powerful.

Epsilon ECHO Cannons have a massive 50% damage penalty against modules, making them unsuitable for base attacks.


  • Each bounce reduces the damage output by one-third.
  • It has a similar firing pattern to the Rebound Ray that is used on the Reaper Harvesters.
