What is KESSLER: Orbital Incremental?

In this single-player incremental shooter, a forgotten military satellite reactivates in 2041 with its original Cold War orders. You aim and fire once per pass, then watch debris collide with satellites and spend earnings on upgrades to reach higher orbits. The campaign lasts about three to four hours, followed by an unrestricted free mode.

For you if...

  • +you enjoy dark humor and science fiction references

Not for you if...

  • −you want continuous hands-on combat rather than watching cascades
