Zero Zone is a futuristic science-fiction adventure and one of the first games that Cryo developed using the 360-degree viewable 3D technology. The game intro exhibits a futuristic city named Megatown, populated by Cybers and Bios. The Bios rule the city and treat the Cybers as slaves and make them work in factories while their females serve the Bios. You play the game in the perspective of someone whose father has been murdered and you have inherited your father's company and his fortune. Your main goal in this game is to assist Agent Ridley in investigating your father's murder and the murderer's motive. During your investigation you travel in outer space, explore the city, search your father's company, and find the computer chip that allows the sensual union between the Bios and the Cybers.

Excellent 3D graphics are displayed in this game and the player uses his mouse to view a 360-degree panned environment and a hand cursor to move forward in the game. Inventory can be accessed either using the control key or right mouse button. Sound and music is quite good along with excellent quality of voice acting. Gameplay is linear and puzzles vary from moderate to very hard while they are logical and mostly inventory based. I would recommend this game to all the fans of science-fiction adventure games with good practice of solving hard puzzles.
