Technocracy has a fairly decent sized map with plenty of room to fight, however, I.M. Phace will immedietely spawn to halt any forward progression. B.B.Bunnies will spawn to give some cash throughout the level, and you can use this cash to fight the I.M. Phace. Soon after, J.K Bun Bun, two Angelic Sleipnirs, and Director Kurosawah will spawn, so you will need to have gained some ground and have some cash to fight them off. Along with the B.B.Bunnies, Kang Roo and Scissoroo will come to the frontlines to assist I.M Phace, J.K Bun Bun and Sleipnir in pushing forward.
The biggest challenge in Technocracy is managing one's cash very well. Because the I.M. Phace spawns so quickly, saving cash early is difficult due to needing to stall him very early on. The solution to this, however, is to use long range attacker stacks(preferably Dragon/King Dragon Cat and Crazed Dragon Cat) that will live a long time, while also being a fair price, to win the stage. A common strategy, though not required, is to use Awakened Bahamut, along with your ranged attackers, to kill the I.M. Phace before the J.K Bun Bun, Sleipnirs and Kurosawah reach your front line. The early B.B.Bunnies and Kang Roo are very important for this strategy because they can net you enough money to spawn Awakened Bahamut while simultaneously allowing you to start stacking Dragon Cats(or whatever ranged unit you decide to use). Maglev Cat can be extremely useful for the opening to this level due to his high damage allowing him to easily create double cash and net you more money, faster.
Once the I.M. Phace has been dispatched, a lot of the battle becomes a stall fest, a test to of your meatshielding to ensure you stack lives for as long as possible to kill off the J.K Bun Bun and Sleipnirs. There's not much to say about this part of the battle, other than make sure to be aware of your cash at all times, and try to have some on the reserves. Once the Sleipnirs and J.K Bun Bun are dead, all thats left is Kurosawah, who, once dead, will be your last main threat, and the level will be complete.
