Steredenn: Binary Stars

As with the other weapon related achievements, you must simply pick up and use all bot weapons once (purple). 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.

Bot weapons consist of:
Gunbots
Stasisbots
Flamebots
Rocketbots
Shieldbots
