This game had fixed u mistakes other game have.
I found this game quite fun and addictive. It delivers an simple game changed in ways to make it better.
The first thing to say is that I am not that into defense games unless you have to defend yourself, leading me to not enjoy the gun turret games or levels. I mostly enjoyed the shooter mode because you can navigate your way to protect yourself instead of protecting other things. In other games like this I would be disappointed to find that i can only play in certain maps if I use the gun turret defending an object. I found that this was saved by the 'Custom Game' feature. The game was also a survival within itself because of the 'Days' that occurred in between levels in which you can buy new guns if you had the money that you collected during the levels.
I found that my favourite mode was the 'Ninja Storm' level where you had to fight 'Shadow Ninjas' with katanas in a dojo. I enjoyed this because you needed skill to fight the ninjas up close. You late found yourself fighting more skilled and upgraded ninjas leading you to buy new weapons such as guns or grenades.
Awesome game
