It's ok – FIREWALL: Defender FREE Review
There aren't any upgrades, there isn't any kind of tutorial, and the 12 tower sometimes shoots at nothing. There isn't even anything to tell what kind of damage the towers cause or how much health the enemy has. It's ok for free but, I wouldn't recommend paying any money for this. It isn't even worth a dollar.
