World at War's zombie mode was an interesting departure from COD's gameplay, but this is ridiculous: A leaked video that is allegedly from Black Ops reveals a top-down arcade shooter unlike anything we've seen from the series.

You can check out the video for yourself while it's still up, but the alleged hidden game mode basically looks like Ska Studios' indie title"I MAED A GAM3 W1TH Z0MB1ES 1NIT!!!1," only much, much prettier. We have yet to receive confirmation that the mode is real, but the video looks pretty legit. What's next for the series, a zombie-themed pinball machine? We can only hope...

[UPDATE]: The video has been pulled from YouTube due to copyright claims by Activision. Doing a YouTube search for "Dead Ops" might find you another temporary clip to watch, until Activision finds that one too.
