Irrational has released the latest video detailing Bioshock Infinite‘s heavy hitter class, this time introducing the Siren enemy type.

The Siren is a haunting former singer who possesses the unique ability to raise enemies from the dead. As creative director Ken Levine explains, this ability presents a challenge for the player: the decision to go after shooting enemies or focus firepower on the Siren, given that killing her means all her minions die, as well.

Meet the Siren in the video below.

Past enemies introduced for Bioshock Infinite include the Handyman, the Motorized Patriot and the Boys of Silence.

Bioshock Infinite is set to be released on October 16.
