What is Pac-Man Battle Royale? This week's Amusement Expo in Vegas explains it all with a playable four-player Pac-Man face off that borrows from both Pac-Man Championship Edition and Super Pac-Man to interesting results.

Arcade Heroes captured first footage of the newest multiplayer Pac-Man arcade "come back", giving us a good idea of how it works (way more informative than that "teaser" spot). The level layouts appear to be the same as the excellent Pac-Man Championship Edition, but the return of the over-sized Pac-Man from long ago, capable of cannibalizing his fellow Pac-Men, adds a new layer of depth.

Pac-Man Battle Royale appears to put more of an emphasis on Pac vs. Pac play, not as much on pellet and ghost eating, an intriguing turn of events.
