The fourth and final of the heavy hitters from Bioshock Infinite has been revealed, and I have to say, I find it the most interesting concept of the four. I love how Irrational Games decided to tie this enemy class closely with the culture of the time period. The Siren looks melancholy, sad, and somewhat creepy. But her design seems to aim more towards 'haunting' and less toward plain old 'scary'. Again, I'm really excited to check out the Siren and the other heavy hitters come Fall. My only complaint with this trailer is the minimal gameplay footage it provides of the Siren in action.
