The listing, Snakes Revenge Nes has ended.
Like in the original Metal Gear, the player's objective is to infiltrate the enemy's stronghold while avoiding detection from enemy soldiers or surveillance devices. To fulfill their mission, the player must collect a variety of weapons and equipment, such as firearms, explosives and rations, as well as card keys to access new areas. If the player is discovered by the enemy, the game will go into an alert phase where enemy soldiers will enter the screen to attack the player. The player must defeat a specific number of enemy soldiers to return to the infiltration phase or go to a different floor or area. In some cases, particularly when an enemy soldier sees the player and only a single exclamation mark (!) appears over his head instead of two (!!), the player can also escape the alert phase by going to the adjacent screen.
