Nose around Helldivers 2's Galactic War map and you might notice that there's a lot of empty space. Around half the celestial sphere is given over to the dominions of the Automatons and Terminids, leaving ample room for another enemy faction to be inserted via free update or paid DLC. What could that next faction be? Surely it can't be any worse than a horde of giant bugs or a legion of robots. Surely it can't be, say, a highly advanced elder species of teleporting illusionists equipped with lightning guns and cloaking devices. Oh dear.
