Alien Invasion

That's not gonna work.

(A group of Kischun soldiers find and kill you. In the second before your death, you see their appearance. The Kischun look somewhat human-like, but with vulpine features like their ears and snout(s).)

(The Kischun destroyed all launch sites to space in the nuclear exchange.)

The nuclear exchange hit French Guiana's EU launch sites, Houston, Cape Canaveral, and other places as a terror-bombing campaign.

(The Kischun start building 23 megacities to house the remaining 5.9 billion survivors.)

Also, humans are allowed outside the megacities.

*uses uno reverse* IM INVADING THEIR PLANET NOW-

You show an Uno Reverse card to Kischun authorities, to emotionless reactions. Nothing comes of this. You're still trapped on Earth.

(A Kischun officer smells poison from something. It turns out to be someone's chocolate bar. The officer confiscates it and throws it out. A total ban on anything with theobromine, a chemical poisonous to Kischun, is enacted. Kischun can also stomach a few chemicals that humans can't.)

(The Kischun set up more infrastructure supplanting humans' creations. Eventually, retails are set up for legal food, clothing, and what little entertainment hasn't been outlawed.)

(The Kischun's national anthem starts playing, the initial bagpipes throwing the crowd for a loop.)

what if... i switch to creative mode?

This is not Minecraft. You cannot switch gamemodes.

(The Kischun's Queen accepts your bow to her.)
