The Thargoids in Elite: Dangerous are an alien race that originally appeared in earlier Elite games, but are now back, with a whole load of mystery surrounding them. The alleged first kill of a Thargoid, however, has gone to Joshua 'Harry Potter' Chamberlain, or rather his clan, the Smiling Dog Crew, who even recorded the feat and uploaded it to YouTube.
Harry Potter reported this feat to Polygon, and the video itself shows the Thargoid ship being disassembled until the heart is available to batter with anti-xeno missiles.
An impressive feat indeed, and a milestone achieved in the expansive sci-fi game. Will you be taking one on?
Thanks, VG247.
