what is the best/fastest way to earn more credits to be able to upgrade equipment? I have been playing for about two weeks and my credits haven't gone up at all it seems like.
you only get credits for advancing a tier - 50 - 100 - 150
you can earn more credits playing Ready Go's (1oocr to enter) you need to win .
or there are the surveys and offers under the GET CREDITS link.
What's a Ready go?
FAQ's. Worth reading. :-)
