This hidden little gem was found today, the last day of E3, and it's a mulitplayer arcade box called Pac-Man Battle Royale.
The general concepts are the same as the Pac-Man we all love but it has 4 players battling for pellets, ghosts, and fruit. The player who lives the longest without being killed by ghosts or other players turned giant wins the round. There are 5 rounds total.
The game is only arcade box currently, a proptype, that will arrive anywhere arcades boxes usually appear. There are currently no plans for XBLA, PSN, or WiiWare.
