Towers (iDestroy TD)

In iDestroy TD, towers are used to combat the bugs instead. To build towers, enough cash must be available which more can be earned by killing bugs before they reach the goal, tower icons that are in yellow color means that tower can be purchased while tower icons faded out means you don't have enough cash. Once placed a tower will be on standby until a bug wanders into range which it'll start shooting until the bug is dead or goes out of range. Tapping on a existing tower pulls up a menu which displays the range indicated by a green circle, a kill counter that shows the number of bugs it killed so far and buttons that upgrades the tower or sells it for a sum of cash. Upgrading towers is the key to survive the later waves provided that enough cash is also present. When upgrading, both attack power, range and firing speed is increased, all towers can be upgraded to level four.
