Here are some Videos how i played the Campaign
Happika: Unlocks Rover Assembly, Mason, Scorcher, Ripper, Ravager
Just be fast with the Scorchers and destroy if u see every Constructor or the Commander, you only need to destroy Mexes to win. This Map can be hard sometimes.
[Spoiler]Cadentem: Unlocks Fencer, Badger
Just capture the Mexes Botom and spam Fencers and some Badgers.
[Spoiler]Baosezu: Unlocks Impaler, Crasher, Dart
First build some Crashers because the Enemy does only have the Gunship Plant and capture fast the Mexes. Later he will build like 3-4 Amphbot Factorys and just spam everything he have. Destroy the Desolator with Impaler and some Factorys too and just spam much Fencers.
[Spoiler]Ganong: Unlocks Dominatrix
This Map is just Luck based, the Commando of the Enemy can be everywhere and u need every Dominatrix u can get so just push and if u get the Commando u won if not restart.
[Spoiler]Skokukur: Unlocks Puppy, Placeholder
Just use the Puppys to get much more and destroy the Factory of the AI, then just spam Pyro and get the Commando bottom right
[Spoiler]Estann All: Unlocks Faraday, Thresher
Build many Shield Units for a good Shieldball and some Constructors, go with the Commando one Site and the Constructore the other Site to reclaim the Zombies and build same Time Mexes + build more Thugs and Rougue or somthing like that.
