Irrational Games has released the second installment of its video series focusing on BioShock Infinite's so-called heavy hitters. These larger enemy types seem to function like minibosses, breaking up the action between run-of-the-mill encounters. In this clip, you'll meet the Handymen. These hulking monstrosities have exposed hearts, porcelain fists, and a terrifying indifference to anything other than destroying Booker.

Ken Levine and the rest of the Irrational team explains that the Handymen have somewhat tragic origin stories, which he doesn't want to spoil before the game hits. In the meantime, all you need to know is that these modified people have huge, porcelain fists, mechanical bodies (with functional human hearts), and the ability to leap great distances. They're also more than happy to toss friend and foe alike at Booker, which makes them a feared enemy no matter where you stand.
