Hypothetical question: You're hanging out in the sewers, when all of a sudden, a radioactive plumber comes flying out of the nearest pipe and right at you! Sluggish to react, the plumber bites you on the arm! What do you now? Stomp really hard on someone's head, then throw his unconscious body into the sewer water, then go back above ground and stomp the shit out of anyone you can find, that's what. And that is exactly why I cannot wait for the 80's Easter egg hunt that is Retro City Rampage.
Side note: how awesome is the music?
