METAL GEAR (NINTENDO NES)

Towards the end of the 20th century, a small fortified nation named Outer Heaven (founded by a mysterious war hero whose name and identity are shrouded in secrecy) threatens the nations of "the West" with the development of a new prototype weapon named Metal Gear, a walking tank capable of launching nuclear warheads from anywhere on the globe. As a new recruit to FOX-HOUND (an elite black ops unit), codenamed Solid Snake, your mission is to infiltrate Outer Heaven and rescue your missing comrade, Gray Fox (who has was captured after a failed infiltration), while gathering intelligence on Metal Gear.

In order to achieve this goal, the player must collect various weapons and equipment (including keycards for later access to the fortress), while avoiding eye contact with the enemy. The player must also face bosses in the form of Outer Heaven's elite mercenary force and rescue hostages hidden in the fortress in order to increase the player's rank, which grants Snake an extended life bar and a increased storage capacity for replenishable items and ammo. The player can use a wireless transceiver to get in touch with his commander, Big Boss, to learn more about his current mission objectives or contact one of the local resistance members secretly operating in the fortress to get useful advice and information.
