Tower defence is more of a niche genre for a particular subset of gamers. The slow pace and constant, strategic management of resources that characterises the games may sound like either a fun time or a monotonous drag to you, but something like Anomaly 2 is, er, an anomaly. Have you ever wondered what it would be like to play as the attacking force – usually the “bad guys” – in a tower defence game? Speculate no further because 11 Bit Studios has answered that question with something it likes to call “tower offence”. We can certainly admire the aspirations of the developer in trying to design something where no game has gone before, but is this alien endeavour too ambitious and experimental for its own good, or is it a commendable push in invigorating its static genre with much-needed innovation?
