Steredenn: Binary Stars

As with the other weapon related achievements, you must simply pick up and use all energy weapons once (blue). There is a bit of luck as weapon drops from cargo ships are random, but you will encounter them all over time.

You can check which weapons you've picked up under the arena menu.

Energy weapons consist of:
Laser
Ultra laser
Lightsaber
Plasma Gun
Boomerang
Shockwave
Death Ray
