The Battle of the Bulge: Tigers in the Snow is a turn-based strategy video wargame, made in 1981 by Chuck Kroegel, David Landrey, and David Walker for the Apple II, Atari 8-bit, and TRS-80. It was later ported to the IBM PC and Commodore 64. It was the first video game to feature the Battle of the Bulge of 1944 and 1945, a decisive Allied victory over German forces in World War II, as its subject. Heavily inspired by board games, the game was played on a hexagonal grid and included such features as a supply, terrain and weather system.
