Irrational Games has released the latest in its series of Heavy Hitters videos, introducing us all to the Siren enemy type. As the team explains in the clip, she's a throwback to when the term "spiritual" meant something a bit different than what it does now.

This former singer has the unnerving ability to raise the dead with her songs. As creative director Ken Levine explains, this creates a bit of a challenge for both Booker and the player: Do you focus your attention on the Siren, because putting her down also instantly kills her minions (again), or do you worry about the guys who are actually attacking you? All we know for certain at this point is that her "song" isn't anything you're going to enjoy.

If you haven't been keeping up with this video series, there's plenty of time to catch up before the game's October 16 release. The Boys of Silence keep Columbia on high alert, the Handymen have giant fists and plenty of pep in their step, and the Motorized Patriots are about the creepiest robotic George Washingtons you're ever likely to see.
