just reading the setting text and watching the clips, at first it kinda seems like standard alien invasion setting, but then nothing about the bot mobs seems alien at all

and if you listen to the video, this is the first words spoken:

there is no way to hide. kings, barons, queens, we give them different names, but they're all the same, killing machines falling from the sky

text descriptions:

ARC Raiders is a free-to-play, reimagined, cooperative action shooter that offers an intense struggle in every session: together with your squad, defend our home and resist the onslaught of ARC – a ruthless mechanized threat descending from space.

You play as one of the Raiders, a rogue group of resistance fighters. With the help of a patchwork early warning system, you fight to protect our home against enemies dropping from orbit. ARC is faceless and unfeeling, but no one could accuse ARC of being unresponsive. In fact, ARC responds to resistance with ever-increasing destruction.

As a Raider, you know that defeating ARC requires more than simply pointing and shooting a gun, and more than one person trying to be a hero. When ARC is around, lone wolves never make it very far.

As underdogs, we need to believe in something bigger than our own strength, in something unapologetically human. That’s why we come together. United amid the unlikelihood of success, what seemed implausible may just become the best course of action. So, by all means, come prepared and plan ahead, but sometimes you just have to wing it.

maybe it just my hopeful caffeinated morning brain, but this really looks like a more realistic climate/cyber punk setting, but I'm probably wrong

it's probably just some evil AI or something ... which is nothing like Capital of course
