This is a skill point.
Very easy trophy. Planet Kerwan will be the first planet you fly to, it's the metropolis type planet with the flying cars. As soon as you land you will see two turnings, one right and one left. Take the left route and you will reach the training ground. The first time you visit a cut scene will occur with the Qwarkbot. You will need to return to this location once you have either the Devestator or the Visibomb Gun, as all other weapons are too weak. With either of those weapons in hand, simply shoot the Qwarkbot to destroy it and unlock this trophy and a skill point.
