Iron Sky: Invasion

Story related and cannot be missed.

You will acquire the Xerg light fighter during Chapter 1. Once you have completed all the objectives for the mission, you can dock at the Korean space station. Once docked you will be given the option to switch from your Dundee to the Xerg. The trophy will unlock when you switch over.

Quick note, this Xerg and the ship you already have, the Dundee, are the only 2 ships that you’ll need to upgrade for the platinum, so don’t bother wasting your money on any others.
