scenario strategy help please!

[tawraste]

Hi all,
Can anyone help? I'm trying to get 100% mega brutal wins. Here's what I have left to do:
Necroa on ice age, global warming and golden age.
Shut down everything, all scenarios except fungus, necroa and worm.
Simian flu on every scenario.
Can anyone help please?
Many thanks
Tawraste
