Many of us love Plants vs. Zombies, but you can only play it for so long. If you have achieved everything, a similar (almost identical) game with a bit of a twist might be what you need. If that is the case, today’s Amazon free app of the day is Humans vs Aliens.
It is the same idea, except this time you are dealing with military personnel and equipment, as well as aliens, meteors and orbs. And if you like social gaming, this is also an Open Feint game, so you can go against the world with all your achievements.
Check out the game for free, straight from the Amazon App Store. If you happen to read this another day, though, the app is $0.99 both in the Amazon App Store and the Android Market.
