Body Harvest is a 1998 action-adventure video game developed by DMA Design and published by Gremlin Interactive for the Nintendo 64.

The opening text tells of how an alien force has harvested the population of Earth over a 100-year time period.

Greece was the first targeted area in 1916, southern Spain was second, eastern Canada was third, and the south island of Japan was fourth.

The aliens attack and board Station Omega, chasing Adam Drake, the game's playable character, through the corridors.

The monitors show his colleague, Daisy Hernandez, telling Adam to get into the Alpha I without letting the aliens gain access to it.

Meanwhile, back on Station Omega, an Alien is shown holding a drop of Adam's blood and eyes it strangely.

[4] Each level in Body Harvest requires the player to stop the aliens from slaughtering everyone in the shield area.

If too many civilians die for any reason (including friendly-fire), the aliens will destroy the area and the mission will have failed.

Vehicles provide significant protection from alien attacks and allow the player to travel at a far greater speed than on foot.

Vehicles take damage independently of Adam and can be repaired with health pickups spawned by defeating larger aliens.

Each vehicle has a unique combination of top speed, armor and fuel capacity, inviting players to consider their options carefully.

In addition, the Alpha I (the ship the player uses to travel through time) becomes a powerful armored hovercraft during boss battles and for the entirety of the Comet level.

There are many buildings in each stage which can be entered on foot, many of which are essential to talk to plot characters and acquire necessary items.

Buildings also contain health pickups, new weapons other than the standard pistol are a machine gun, shotgun, rifle and rocket launcher that each use different types of ammunition.

With thorough exploration, rarer items can be found including alien artifacts and 'weapon crystals', three of which combine to form a technologically advanced powerful laser weapon unique to that level.
