Pac-Man Mega Tunnel Battle plays similarly to the original Pac-Man arcade game. However, the game has 3D-graphics and up to 64-players can play at a time. The players begin in their own mazes before more areas get unlocked. Once the player eats a power-pellet, the player can either eat ghosts or other Pac-Men like in Pac-Man Battle Royale or Pac-Man Party Royale. If the player gets eaten by a ghost or another Pac-Man, the game is over.
The original Stadia version of the game received mixed reviews from critics. The reviews liked the battle-royale format of the game, but criticized it for its lack of content and its pricing. Elisha Deogracias of Gaming Trend noted in his review that there are better free alternatives such as PUBG: Battlegrounds.[5]
