Threat and Orbital boomstick charging First time I'm reaching the phase of charging the Orbital Power Transmitter.  A few minutes after, I got the "20000% threat" achievement.

It is an interesting challenge!  Missiles are flying constantly, and my base is a coal chugging turret porcupine.

But, I'm just curious if I'm playing it correctly as I don't know what to expect from this stage of the game. Is it supposed to be this intense at this stage of the game, or am I just being very bad at threat management?
