** SALE: To celebrate the release of Spira 2, all my X Defence Pro games are discounted!
A tower defence game with a twist. You must defend your base from enemy attack by building / upgrading defence towers. Money is awarded for kills to spend on upgrades. Interest is earned on the money not spent.
** Samsung Galaxy S2 Issues: If the game is randomly crashing for you, please play with the sound off from the options screen. I'm working to find a solution.
