This is the home page for Afternoon Stalker, a robot-killing video game. It is a clone of the 1982 Night Stalker video game for the Intellivision, from Mattel Electronics.

Afternoon Stalker 1.1.6 is out (2019-11-11). This version links with version 0.1.7 of the flatzebra library. In version 1.1.4, a minimal maze was added to the game (selectable from the Options sub-menu). The Maze menu was improved to display the selected maze while in the menu.

Requirements (on a GNU/Linux system): SDL, SDL_image, SDL_mixer. The sources might compile on other Unix-like systems.

My personal high score is 41800 (June 29th, 2008). If you beat this, write to me and I will display your score here.


You need to get afternoonstalker and flatzebra. Your system is assumed to already have the required SDL libraries.

Game Play

The command afternoonstalker runs the game. If you use GNOME, you should see an entry for Afternoon Stalker in the Games menu.

Use the arrow keys to move and the Ctrl key to shoot in the direction you last walked. You can also shoot in a fixed direction with the H (left), J (down), K (up) and L (right) keys (this is the same convention as in vi). The Escape key pauses the game and shows the main menu. The P key also pauses the game the same way.

Alternative Rules

The game's Options menu allows you to change the maze and the rules. The "Alternative" rules are slightly different:
  • The game starts with 5 robots instead of 3, and the number of simultaneous robots increases more quickly.
  • There are only gray and blue robots, but they move slightly faster.
  • The number of bullets in a gun increases as the game progresses.
  • Bonus lives do not come as often.
