Vector Siege TD
Vector Siege TD - new fun addicting tower defense game with multiple levels and many skills you can upgrade along your way. There are 9 towers, but 5 of them will need to be unlocked by using XP to get the tech level upgrade. To build the last tower, the Ultimate Tower, you will need the gems upgrade. There is a limit on how many ultimate towers you can build, because building them without limit would just be too ultimate. To build a tower, simply drag from the tower menu at the bottom and place it on a valid place on the map.
