However, the radar is disabled when the game enters Alert Mode.

A radar with a 3x3 grid on the upper right hand screen shows Snake's current position in the center screen (as a red dot), with enemy soldiers as white dots, allowing the player to determine what's ahead. Players can also pick up land mines and hide in tight spaces such as under desks or inside air ducts. For example, the player can now kneel and crawl in addition to walking, allowing them to avoid making noise. The player has been given new maneuvers and tools to help them remain undetected. When the counter reaches zero, the game returns to normal. When the enemy loses track of the player, the game enters Evasion Mode and a counter will go down. If the player is discovered by the enemy, it will trigger Alert Mode and the number of life points they currently have will be displayed on the upper right side of the screen. The enemy can also hear any noise made by the player which usually occurs when the player fires a non-silenced firearm, uses an explosive, hits a wall or walks on certain types of terrain. The guards can also turn their head left or right to see diagonally and move from one screen to another (instead of being stationed in one area).

Unlike the guards in the first game that could only see in straight lines, the guards in Metal Gear 2 can see in a 45 degree field of vision. The biggest change in the game was the enemy's behavior. As in the original Metal Gear, the player's objective is to infiltrate the enemy's stronghold while avoiding detection from soldiers, cameras, infrared sensors, and other surveillance devices. Metal Gear 2 builds upon and further evolves the stealth-based gameplay of its predecessor. The game significantly evolved the stealth-based gameplay of its predecessor "in almost every way," introduced a complex story line dealing with themes such as the nature of warfare and nuclear proliferation, and is considered "one of the best 8 bit games ever made." However, the game was not released in the Western world, due to the conflicting release of Snake's Revenge, until 16 years later. In the game, Solid Snake must infiltrate Zanzibar Land, a heavily defended territory located in Central Asia, to rescue a kidnapped scientist and destroy the revised Metal Gear D.

A North American and European version of Metal Gear 2 was released in 2006 as part of Metal Gear Solid 3: Subsistence along with the original Metal Gear. The game was re-released as a downloadable game for mobile phones in Japan in 2004. It was initially released only in Japan for the MSX2 computer on July 20, 1990.
