The hysteria from fanatical purifiers over having alien squad members in an XCOM game have been amusing.
As someone who played (and still plays) the original X-Com, I find the entire idea behind this disturbing.
Which? The interspecies relationship that's a fantasy/sci-fi trope of its own, or people wanting XCOM to be grimderp omnicidal maniacs? Granted, there's still some context required: in XCOM2, you're leading a resistance force to retake Earth from the Ethereals and their Vichy puppet ADVENT. It turns out that the vast majority of the aliens, including ADVENT forces, were mind controlled via psionic neural chip, and many of them rebelled when the signal was disrupted during the final mission. Chimera Squad, the new game, is set 5 years later, and humanity is now having to share a liberated Earth with stranded alien refugees, not unlike some aspects of Apocalypse.
