A different kind of adventure game, Hacker contained no instructions or clues other than some simple loading instructions common to any game. All you saw when you first entered the game was the word LOGIN. You needed to figure out the rest of the game yourself, which turned out not to be easy. Though the game was primarily a treasure hunt adventure where you ferried objects between people and continents, Hacker was a very original and unusal concept that worked out rather well and was still somewhat difficult. If you can find it around today (unlikely, but probably not impossible), it is probably worth your time.
