Tower defense games are a dime-a-dozen these days, with plenty of them flooding our consoles, PCs and especially mobile devices. Tweet Defense is looking to change things up a bit by creating another tower defense game that integrates your twitter account in order to kill zombies on the go.
Inside Social Games has a neat writeup with many details on the game, explaining how gameplay works and how twitter integrates into the way it is played. The more twitter friends you have, the easier the game will be because you will have a higher rate of fire on your towers. More followers gives you greater range and the number of tweets you have will increase the amount of damage you have.
Tweet Defense sounds like one of the most robust integrations of the feature yet and I think it would be very interesting to see how more and more games integrate certain aspects of your twitter account.
