A DOS computer Action-adventure game based on the first movie. Developed and published by Bethesda Softworks in 1990, it was the first officially licensed game based on the Terminator film series.

This game was written in 100% assembly and takes up more than 35000 lines. The game contains approximately 20000 3D objects. It was developed using Turbo Assembler and Turbo Debugger with all debugging being done remotely. It was created on a variety of 286 and 386 computers. All graphics were created on IBMs and Amigas using DPIII and DA. More than 700 frames of animations were created. The delta mode compression yielded a 100 to 1 ratio.

You take on the role of Kyle Reese and protect Sarah Connor from the cyborg sent back in time to kill her, or become the Terminator and eliminate Kyle and Sarah. Either way, the player chases his opponent through Los Angeles buying or stealing weapons and equipment while attempting to eliminate his enemy and avoid the police.

The game takes place within a huge (roughly 10 miles by 6 miles) 3-D rendered area of central Los Angeles. The game area runs roughly from Beverly Drive to Central Ave (lengthwise), and from Mulholland Drive to National Blvd (vertically). A game map is included in the box for reference. Though the buildings and their placement within the world is generic, and highways/overpasses have been removed, the streets and their layout are largely accurate. The game also includes some landmarks, such as Dodger Stadium, Griffith Park, and the Silver Lake Reservoir.
