Lost Patrol is an action / strategy computer game developed by Shadow Development and published by Ocean Software Ltd, released for Amiga computers in 1990 and the Atari ST in 1991. A DOS version was later released by Astros Productions. Despite appearances, all graphical cut scenes except the black and white in-game animations are hand drawn, not digitised.
The game is set during the Vietnam War, where on June 7, 1966, a U.S. helicopter, returning troops from a rest and relaxation break in Saigon crashes in remote highlands of Vietnam. Seven U.S. soldiers, survivors of the crash, face the task of trekking across 58 miles of harsh terrain infested with booby traps and enemy soldiers and make their way to Du Hoc, the nearest U.S. military base. The team has little food or ammunition and their chances of making it home are slim.

Ocean Software (or Ocean Software Ltd. and sometimes Ocean of America, Inc. but generally only referred to as Ocean) was one of the biggest European video game developers of the 1980s and 90s. The company was founded by David Ward and Jon Woods and were based at 6, Central Street, Manchester. Ocean developed dozens of games for a variety of systems such as the ZX Spectrum, Commodore 64, Amstrad CPC, Atari ST, Amiga, PC, and video game consoles such as the NES and SNES.
