Tip 1
When you need to get through mine fields, draw a tight and tiny circle to make your formation crowd together.

Tip 2
Get just close enough to shoot, then back off a bit and stay just close enough to get some shots in but far enough that you can run as needed.

Tip 3
Test your strength. After you finish placing all of your defensive implements, attack your own base.

Tip 4
You can get free coins by going to the shop area and watching the "Propaganda", or advertisement videos.

Tip 5
You can get free Prisms, the premium currency of the game, completing the various missions that the game gives you.

Tip 6
If you run over mines fast and run away from them before they blow up, you will take absolutely no damage.

Tip 7
Scroll sideways when you go to the skills menu, because there are far more skills than appear on the initial screen that you open.

Tip 8
Turrets and the troopers make a deadly combination together. Turrets take forever to take out and will constantly harass the attacker, making it a huge ordeal for them to take over just one tiny little strategic area.

Tip 9
Turret tanks are equally effective against attackers.

Tip 10
If you want to earn experience quickly check for daily achievements to come up that give you experience points as a reward for unlocking them.
