JCWest said: Minimize battle participation to extend your cargo availability.The game won't reset for twenty-four hours until you expend all your available cargo capabilities. Once expended, you can reset your cargo with blue diamonds, and in turn fight opponents to gain their oil and minerals once again, until reset cargo is expended. And, this in turn will allow you to upgrade, progress, and continue the fight throughout the day.Also, focus on oil (1), mineral (2), and generator (3) upgrades, as they are cheap and an easy way to level up. You will need these most in progressing forward. Do this until level 7. Good luck,YO, JOE!!!
RickOShay said: For those of you who find it difficult to keep enough Minerals on hand to keep fighting, simply spend 15 Diamonds on the 30,000 Minerals (do this on Oil at least once also). Save your Diamonds only for this, and sometimes to speed up Cargo. Don't spend Diamonds on speeding up upgrades. You will get a lot of "Speed-Up" items to do this otherwise.
RickOShay said: Also, when selecting battles, look for a base to attack that has a decent balance of Minerals and Oil to be rewarded. Be sure to destroy their Mineral deposit buildings to earn those rewards during the fight. You may need to save up some Credits (gold) to skip opponents until you find one with good rewards.
