"This is how you finish your last mission
*completed all default missions for Arm
*completed all default missions for Core
*completed krogoth encounter
*completed CC missions for arm
*completed CC missions for core... this being the 12th and very last mission.. I decieded to go crazy and NOT do the fastest walk to victory :

-completely fix and improve the fortress, but maintain the style
*expand the defend to the back, completely protecting the fortress from all sides.
*completely remove wall sections than replace them as follows :
toaster - 1/2 wall space left empty - 5 fortification wall -1/2 wall space left empty - viper -1/2 wall space left empty - 5 fortification wall -1/2 wall space left emptyl - toaster
*increased the wall to contain 24 toaster, 23 viper, 238 wall pieces, also build 8 pulverisers to surround the implosion devise and the repair pad (also build a targetting facility near the one surviving air-repairpad)
-make sure every one of them gets veteran status
*go on the offensive and capture a building, to aquire acces to the arm AND core building tree
-ofcourse you build all buildable buildings of all factions, including harbours, seaplanes and the krogoth gauntry)
(build for both factions 1 normal conplane and 14 adv. conplanes, for fast building of whatever you want, delite all other conunits)
*build a moho mine on each of the 8 iron spots, surround each of them with : 2 cobra, 2 doomsday machine, 2 annihilator and 1 Intimidator (also boost them to veteran status)
*build 20 arm moho metal makers, and 16 core submerged fusion reactors, as well as 4 submerged metal mines.
(not that you neeed it but heh it's for show)
*build 14 more krogoth (now having 15) and 15 hawks
*build 5 nuclear facility's each with 50 nukes in them (250 in total)

than in one great blast, unleash every weapon at your disposal at their ONE remaining wind powerplant you allowed them to keep. (with a gametime of little over 7 hours played for one mission, while you could have finished it after 60 minutes)

WIN!"
