Defence Cannon

Defence Cannon - sort of a genre of tower defense for Android. You have only one, but very big and powerful gun, and your task will be to protect a convoy of trucks and barricades from the hordes of giant insect robots. Rotate the cannon 360 degrees and shoot from the attackers.
The gameplay is of course repetitive, but can pass the time and enjoy the superior graphics. The management of backtrack slightly, but quickly developed. Rotating your smartphone or tablet, you can look at the battlefield from a different angle.
