General Tips
- If you're having problems with a particular stage go for a duel or survival round and play some in order to get coins. Then use those coins to upgrade your weapons, armor, and helmet and then go for the troublesome stage.
- You can only duel once every four hours so just forward the time on your phone in the time settings and you'll get your dueling privileges again.
- Body armor should be first on your shopping list as it will increase both your attack power and your defense.
