More espionage than hacking
The game is an old take on the idea of hacking from beginning of 80s. Maybe inspired by those classic movies of the time such as War Games. However, there is not that much of hacking indeed as the concept of the game is to go around the world and talk to different "spies" in order to buy and exchange items and get back a piece of some important document you'll have to bring back to CIA. The only hacky part is the beginning of the game where you must guess a series of parts of a robot in order to get in the game system. Not sure if that was on purpose or a sort of copy protection where you needed some manual, but you may spend quite some time by guessing (or just watch the video instead...). The gameplay is quite straightforward. You must navigate through a sort of tunnel from one city to another in order to meet those spies. The controls are the capital letters of the actions in the menu and the arrow keys for moving around. The sounds may be annoying as it's coming from old pc speaker and it's just noise. You'll end up turning it off. Resuming, a classic old game that does not go too much beyond its title.
