-- And distributed-defense is now immediately possible from the beginning of the game, so long as you have the necessary metal and energy production.
My Energy! Where did all my energy go?!
*looks at the thousands of turrets*
Huh. I guess that's where it went.
So now it takes 32,250 Knowledge to unlock all the Mk II-IV general turrets (Not HBCs, tractors, Gravs, anti-*, etc).
This gives you 1,008 turrets on EACH planet, costing 3,110,400 Metal to build, 633,600 Energy to maintain, and dealing 116,145.6 DPS (old 11,614,560 DPS).
And on one chokepoint planet, you can build the Mk IVs, costing another 1,036,800 Metal, using another 211,200 Energy, and dealing another 64,871.2 DPS.
All together, that's 4,147,200 Metal, 844,800 Energy, and 181,016.8 DPS (old 18,101,600 DPS).
But still... Every world needs a ZPG to fully defend itself now
PS: Is there a reason most turrets don't follow the usual Mk II = 2 x Mk I, Mk III = 3 x Mk I damage progression anymore? It's only minor variation (except Flak) but only the Needler and Laser actually follow it perfectly.
