I have the solution guys:D In the ''normal'' fuel-tanks you have two internal tanks, because that is how it is in reality. However you can chose from a list what goes in these tanks. Like I could say both where oxygen. Then for each tank there is a slider too.
These to can be combined to the same so... You can fly around in your Mech, however it meets a Dalek and gets EXTERMINATED. I wish for a weapon that can kill time.
I think Bronies are pretty flippin wierd, however I only dislike those that can't shut the hell up about it. I mean its the same reason nobody likes Jehovah.
