I don't think upgrading Thunder is the best choice for medium to long distance fights. :) I use M1 Smoky and M1 Mammoth which both didn't cost too much. :) :tank:

Ok, but you are at a really high rank. I've even played with the Generosillsims(I can't spell that)

Upgrading hulls is not so expensive and I upgraded my mammoth hull about 3 mouths ago but upgrading weapons such Thunder is pretty pricy. :o
