IBM PC version of Agent USA
is an educational game for children designed to teach geography and time zones. The game's story features a fuzzbomb that is infecting U.S. cities; each city the fuzzbomb infects has all of the people turned into fuzzed people (also referred to as FuzzBodies) who wander around randomly. The player's goal is to visit each infected city and return the fuzzed people to normal and then stop the fuzzbomb.
The player needs to travel to each city infected with fuzzed people by either normal trains or high speed trains (with high speed trains only being available to larger cities). The time zone changes based on the location of the city, so this will need to be taken into account when determining train schedules. While in each city the player will encounter people wandering around; some will be normal, and in an infected city some will be fuzzed. In capital cities there are also information booths which show a map of locations, infected cities, and the location of the fuzzbomb.
The player begins the game with 10 crystals. More crystals can be generated by dropping them in an open area where they will slowly multiply and can be picked up. A fuzzed person is returned to normal by dropping a crystal near them and allowing them to run into it. If a normal person is touched by a fuzzed person, they will also turn into a fuzzed person. If the player is touched by a fuzzed person, crystals are lost. The player becomes a fuzzed person also if touched while holding no crystals.
To win the game, the player needs to build up 100 crystals; once that is done, the fuzzbomb needs to be located and the player needs to touch it with the crystals without being touched by a fuzzed person.
