If you haven't quite gotten over the idea of a Sharknado, an enormous Blue Whale might not make you feel much better, but luckily Ookujira - Giant Whale Rampage is only a game.
In what might be one of the oddest concept I've read this year, Earth is under attack as evil aliens are invading cities. With human technology rendered useless it's time to kick alien butt as a - uh - massive whale.
Rampage through the levels, destroying alien spaceships and bashing buildings so hard they literally sink into the ground. With easy-to-use but difficult-to-master one-touch controls, it's a cracking game for filling in those spare moments.
Already released on iOS, Ookujira has finally released on Android so grab it free-to-play here on Google Play.
