[X] Plan: Walls Forever! Build engineers to keep building more and more walls around the ultralisk until the orbital platform hits and takes them both out. Continue with the rescue.
[X] Operation: Aggressive Turtling - cash in your Economic Outpost sparks to get +3 to buying gear, then buy Turrets for diff 9, taking 4 heat to do so. Then, attack the Mutalisks with your vehicle weapon skill. Augmented by turrets, your damage and range work as secondary characteristics, negating their people (3) to nothing! Diff 5+1 vs your skill of 2 allows you to succeed for 4 heat, putting you at 2 overheat - adding +1 Shock and dropping your heat to 0.
[X] Plan: The highest ground
-[X] Use the Planning sparks and Leadership skill to create Air Transport sparks on ourselves and the parashields.
-[X] Use the Economic Structures sticky spark to make Charging sparks for ourselves.
[x] Plan: Slow It Down - use your nanofabricate skill and your Planning sparks vs diff 1 to create Mass 6 (Mass 6 (Big Cube 4) to try and slow the Ultralisk down. Then begin to charge up your antimatter cannon by using Vehicle Weapon vs diff 1+1 to create Charging 1 spark, then take 6 more heat to create even more Charging sparks. Then turn your Economic Structures into Charging 6, to give you a total of 13 Charging sparks. Vent 6 heat using Just as Planned to get 1 Planning Spark - and plan to charge some more. (You need to be able to get 24 Charging sparks in total to blast through the Ultralisk's durability.
[X] Plan: Killbox - Pin the zerg experimental in place by surrounding it in calcicrete walls and switch the land factory over to building Flapjack mobile missile launchers. Direct the produced MMLs towards bombarding the monster with cruise missiles.
