System Defender tips

Here are some tips to help you play System Defender:

• When you have earned all the system defender stamps you get double the coins each time you finished system defender! (I have done that!)
• When you put cannons down place 2 of the same next to each other so when one is upgrading the other can still continue firing.
• If you have not yet got all the stamps, when you play System Defender remember to concentrate on one stamp at a time, don't push yourself.
• If you have completed a level, but struggled on it. Do it again. Make sure you can do it properly.
