In Global War, players compete against one another for world domination. Gameplay is adapted from the popular board game Risk. The world is divided into six continents and 42 countries. Players decide where to amass armies for defense -- and offense. The player who first captures every country on the map is the winner.
Like many other BBS door games for the PC, Global War's interface and maps are rendered in ANSI. But Global War also offers a front-end client called GWTERM. This custom terminal enables a mouse-driven graphical interface.
