The Unofficial Apple Weblog reports that a new tower defense game is coming to your iPhone and iPod touch next month. But Promethium Group (the former MS Gamerscoreblog crew) has added a twist to the new game Tweet Defense. In what might be the worst thing to happen to electronics since the first person decided to sell Viagra by e-mail, the game awards points to strengthen your tower based on how much you use Twitter.

The premise is straightforward enough. An attempt at the Genetic Synthesis Biolab to create human clones to do video game marketing has gone horribly awry and turned half the world's population into brain-eating zombies—and really, who can't identify with that? But now they are after your brains. Let the comments section go wild over the premise that those who avoid marketing are the ones with desirable (and tasty) brains. For only $0.99 at launch (though they strongly hint that will be a limited time offer), you will be able to build protection from the walking undead on 10 different maps, with 5 types of enemies, 6 tower types, upgradable weapons and so on.

According to Nelson Rodriguez, executive producer, “We wondered what it would be like to take your social network and your activities there and turn it into a game. We ended up with a full on tower defense game that uses your friend list and your tweeting activity to impact how powerful your towers are.”

There are no hard stats on how many people have been unfriended on Facebook because of the barrage of messages from Farmville discussing their friends' eggs and who fertilized what, but this could surpass it.
