If there's one thing Civilization VI is missing, it's aliens. A study done in 1501* found that aliens make strategy games better in almost every instance, with the exceptions being games that already have aliens in them. Now you can unleash some interstellar interlopers on your foes thanks to a new Civ 6 mod.
Better yet, these aliens look like the ones from Firaxis' other iconic turn-based strategy game, XCOM. By building a new world wonder called Area 51, your empire will be gifted one UFO unit, and some 'Alien Infiltrators'. You can train more infiltrators, but they cost increasing amounts of faith. The UFO unit can't be replaced, but creator JNR mentions that the unit is as strong as the existing late-game unit Giant Death Robot.
The UFO also comes with a unique promotion tree that can either make it more potent or buff your infiltrator units as they don't come with their own promotion trees. We're not actually sure what the infiltrators do, as there's no further information given, but we can take an educated guess.
