2K's gone live with the final video in its heavy hitters series for BioShock Infinite. The Siren has been introduced as the fourth and final member of that group. It can bring back foes you've faced before from the dead before taking you on again. As Ken Levine says in the video, the problem will be choosing between the enemies brought back by the Siren or the Siren itself. Get the video below.
The Irrational shooter launches on October 16 in the US and October 19 in the UK for PS3, 360 and PC.
