Everyone calls it first contact — an invasion from somewhere out there. They are wrong. The rifts opened from here, and someone you were supposed to be able to trust turned the key. You are one Orbit operative in the wreckage, following the incursion backward, city by city, to the hand that opened the sky.

Kill Orbit set out to be a multiplayer shooter. It isn’t one any more — and that turned out to be the best thing that ever happened to it.

What it is now is a single-player campaign: a run of cities, twenty missions apiece, every one of them finished before the next city opens — and open for good once you’ve cleared it, so you can go back whenever you like.

Los Angeles is standing. So are Las Vegas, Paris, New York, Hong Kong, the station, and the Moon. Traffic runs their streets on real lights and real lanes, people walk them, and every car you see actually starts. Mars is being built now, and it’s the last one.

Multiplayer is parked, not cancelled. The campaign comes first, because the campaign is the game.
