This normal game has everything. There should be 6 turrets in the normal game mode. In the normal game mode you start with $600 and you get $5 for killing each and every enemy. Some enemies have higher health. In the normal mode there is a bank which would given you money every 3-7 seconds. If you run out of health the game over screen will tell you how many waves you have completed. The second game mode is called deflation. This game mode will give you $5,000 to spend on turrets and there is no bank in the deflation mode and you won't earn any MONEY. So spend it wisely on turrets. This game infinite.
