So, I can't help but wonder. If this is an advanced race of creatures, they must be able to tell that our satellite network is our main resource of communications. Why don't they knock out the whole thing? It's not like we have the resources to protect our satellites from advance alien fighter craft that are superior in near-zero atmosphere. This would make it very difficult to base a game around - no satellite, no gps, loss of a lot of things required to justify how we are able to combat aliens.
Maybe there's something in the story that explains this, but I'm not sure where that would be.
