Play Agent USA Online

Game Overview

Agent USA is this weirdly charming MS-DOS game where you play as, well, an agent hopping trains across the US to fight off this "fuzz" infection turning people into mindless wanderers. You start with 10 crystals—drop one on the ground, and if there's space, it multiplies like crazy. Problem is, civilians will snatch them up if you're not careful, and fuzzed people will drain your stash if they touch you. Lose all your crystals, and you become one of them, just shuffling onto random trains until you bump into a crystal again.

The train system’s oddly specific—you have to type city names exactly as shown, and time zones actually shift as you cross the country. Bigger cities are chaos: more train platforms, more people, and way more fuzz spreading like a bad rumor. You’ve gotta drop crystals in front of infected folks to cure them, but the real goal is farming up 100 crystals, finding the moving Fuzzbomb city, and touching the bomb without getting mobbed. It’s janky, tense, and weirdly satisfying when you pull it off.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
