Dead Zone (デッド ゾーン, Deddozōn) is a text-based adventure video game developed and published by Sunsoft for the Famicom Disk System in Japan on November 20, 1986.

Five months later, Cark, accompanied by his robot Carry, decides to visit Mary and prepare the ceremony at last, but when he arrives at the space station where she is in, everything is quiet.

He wakes up sometimes later, inside a sort of underground graveyard, with pieces of dismantled robots surrounding him (including Lionex (ライオネックス) from Sunsoft's unreleased Nintendo Vs. Series title of the same name).

The bottom of the screen proposes simple action commands, like see, take or push, but the game is entirely in Japanese (although it uses katakana exclusively).

One of the original features of the game is to use real sampled sound in some places, which was unusual for the time.
