You were hunting in the Amazon when you become the hunted of prehistoric creatures. You found a fortress with a large gun. Now you must avoid the snakes that enter and exit and shoot the creatures through the holes in the Sssnake fortress bricks.
The snakes will slither from one side on the screen to the other then come the opposite way one level lower. You cannot kill the snake but you can shorten it when you shoot it. Your gun runs on a gun track inside the Sssnake fortress walls and always shoots away from the fortress. You cannot shoot through the bricks themselves, only in between them.
In this action & adventure game for the Atari 2600, you must navigate your character's gun to hit prehistoric creatures that appear through holes in the fortress walls. The game features two levels of snake speed and a scoring system where you earn points for hitting creatures.
The game offers a single-player experience with two difficulty levels, and local multiplayer support for a second player using the right joystick. Each level requires only one life, and losing all your lives results in having to reset the console to start again.
You score points by hitting prehistoric creatures that appear through holes in the fortress walls, with no points awarded for shooting at bricks or the Sssnake itself. The game's scoring system rewards you for hitting creatures, making it a fun and challenging experience.
