Ionic

Game Description

Ionic is a very detailed space defense game using elements of both tower defence and shoot em up games. Lead your mothership through a massive space battles, while building more and more defensive turrets. Although Ionic is an obviously a tower defense game at heart, the developers tried to avoid some of the more common cliches by trying to move it into a fast shoot'em up.
