Just bought geodefense, a new TD game. it's on sale for a $1 right now. For those of you who like TD games, you owe it to yourselves to check this one out. it's pretty awesome (IMO better than Fieldrunners, 7 Cities, and Tap Defense, which I have all 3). retro style old school graphics and sound. but be warned.... the game is VERY HARD. but not hard where you want to throw the phone at the wall hard. it's hard where you see how each level a small change in gun types or gun placement will make a MAJOR difference and you keep trying new strategies. check it out.
