Frenzy Arcade (Stern) 1982

Frenzy is a multidirectional shooter arcade video game published by Stern Electronics in 1982. It is a sequel to 1980's popular Berzerk; both games were developed by Alan McNeil. Frenzy's gameplay is fundamentally similar to Berzerk-the player enters a series of maze-like rooms containing armed robots and must shoot them to survive-but adds more variety. Ports were released for ColecoVision and ZX Spectrum.
The player must navigate a maze full of hostile robots. The goal of the game is to survive as long as possible and score points by killing robots and travelling from room to room. The game has no end other than the player losing all of his or her lives.
The player has a gun with which to shoot the robots, and simple intelligence of the robots means that they can often be tricked into shooting one another. If the player lingers too long in a room, a bouncing smiley face (known as "Evil Otto") appears, and relentlessly chases the player. Evil Otto will destroy any robots in his way, and can move through walls.
