Arcade Game: Berzerk (1980 Stern)
To advance through the game, players must fight their way through each room to an opening at one of the far walls. Each robot destroyed is worth 50 points and while it’s possible to progress without killing every robot in each room; destroying all of them will earn the player a per-maze bonus (worth ten points per robot). The game has an impressive 64,000 mazes, with each level designed to be more difficult than the last. The game crashes after 64,000 levels.
However, I found a link from someone playing up to 64,000 levels and reached a kill screen. If anyone is interested, you may watch below.
