To get this achievement, you're gonna need a friend to join you in the map U.S.S Anomaly.
You will both need energy swords. To craft it, use the payphone to find out what materials you need. You will need 70 intellect as well as the broom handle, the energy module, and a wire. But that's just to make 1 energy sword, and you need 2. You'll easily find broom handles within other inmates' cells, however the best way to get the batteries and wires is to beat up the police officers, as they typically have a battery and a wire in their inventory. After crafting both energy swords, give one two your friend, and after you each hit eachother once, you'll both get the achievement.
