If I could get on Terran Legacy from my phone I would set you up with some cash to get a better weapon. Unfortunately I don't have a computer handy most of the time at the moment. Keep trying to grind it out and when I can I'll send ya some cash, unless someone else here does first.

Only suggestion I have for you currently though is make sure you put all of your money in the bank before you die. Any cash you have on your person when you die gets cut in half.
