Your mission in this action defender game is to use your shield to defend your base against attacking tanks. Use YOUR MOUSE to move the shield and reflect the projectiles back towards the tanks to destroy them. Every 5 levels you will receive a bonus point which can be spent on special upgrades. Note, you earn interest on the money you save every time you click the Next Level button. Be sure to save as much as you can to maximize your buying power at later levels. After purchasing repair kits, you can use them in the middle of a level by clicking the repair button on the side panel. After purchasing the Sticky Shield upgrade, you can fire stuck projectiles by clicking anywhere on the screen or by pressing SPACEBAR. Lets play!
