There's a new tower defense game on Android seeking your eyeballs and your money. It's called Prime World: Defenders and you can play it on Android and Facebook today with full gameplay sync. Yeah, you might hate Facebook, but not everyone does.
On the surface this is a traditional tower defense game – all the usual upgradable towers and waves of creeps are present and accounted for. In addition to all that, however, there's a collectable card element to Prime World: Defenders.
