Dreaming about a golden icecream cone that lived in a boy on sunday.....I guess I`ll only eat icecream on sunday then, dont wanna kill no cone, they shall live forever!
For the last level though, I used a different strategy, maxed out production, and all of the Scout ship upgrades, then maxed EMP Charge and Wave and Special regeneration. Turn on autobuild (press 0) in any single lane and just spam EMPS and mines like a madman whenever they warp into your ship or anything gets close enough, wave it back. Easy as pie, takes under three minutes to win like this, scout ships madness!
The easiest way, in my opinion, to beat the human campaign is by giving the missile frigate the ability to attack multiple lanes, max missile attack and frigate armor, then spend your money on EMP charge and Sonyenergy to spam the stun effect every few seconds. Of course you gotta maximize your production points first. Hope it helps.
