MS techs + platforms

[dominater92]

How many of them are there? And what would be a cost effective level to stop at with a small MS of capacities 10K-20K?

Also, what happens with the cost of planet defence platforms as you ascend, do they get cheaper or more expensive?

costs of platform
stays the same

ms techs max 10 levels disappear upon ascending
=> if you plan on ascend don't buy them at all
