Heard this said by Guildenstern in the video game Onimusha: Warlords - "Nan do chu?"
What does it mean? I asked my co-worker who is a native speaker from Japan and she said it doesn't mean anything.
But it seemed like she knew, but didn't want to say... I may be mistaken. She's hard to read.

Here is a video of the scene where the phrase is spoken at time mark 1:43.
Thanks a lot!
