So that's what they were saying!
A new version of the first trailer for Killer is Dead, originally released back in January, has appeared on the interwebs which features the game's English voice acting.
I think my favorite part of the dialogue is when (what I can only assume is) a villain says, "you don't understand anything, do you?" You know what? You're right. I don't understand anything that happens in Suda 51 games. That's why I play them.
