One of the most fondly remembered arcade games of its era, Berzerk combined fast shooting action with (at the time) groundbreaking speech synthesis samples – many of which have been sampled in assorted songs and other video games in tribute to Berzerk. Most of these samples came from the robots who were the player’s main enemy in the game.
The main enemy of Berzerk, Evil Otto, appears to be a malign basketball, but he is also the only arcade game villain to have caused deaths in the real world, with two different people succumbing to heart attacks (as teenagers, yet) after marathon Berzerk sessions.
