->''Station Omega: Earth Orbit: 2016. The Earth lies in ruins. Over the past 100 years a vast alien invasion has harvested mankind to the brink of extinction. High above the dead planet, the last survivors hatch a desperate plan to halt the invasion at key points in the Earth's past. A prototype time travel device is ready. It's crew, a team of genetically enhanced super soldiers, is being prepared. But time has run out. The aliens have returned. And they're hungry...''
''Body Harvest'' is a [[URExample proto]]-sandbox game by DMA Design (now Rockstar North) released for the Nintendo64 in 1998. It is a [[SpiritualSuccessor spiritual predecessor]] to the ''VideoGame/GrandTheftAuto'' series.
The plot goes as follows: An insectoid alien race has [[ToServeMan harvested]] humanity over a period of 100 years starting in 1916, using shields to prevent anyone from leaving or entering the harvested country. The story begins when the aliens try to wipe out the last humans survivors on the space station Omega in the year of [[TwentyMinutesIntoTheFuture 2016]]. The player character, Adam Drake, escapes but not before being wounded by one of the boarding alien. He manages to get into the [[TimeMachine Alpha 1]] and is transported to 1916's Greece, where the game starts.
It is quite notable for introducing many of the elements now used in most 3D [[WideOpenSandbox wide open sandboxes]]. It is possible to explore the environment at will and do the objectives in non-linear orders. Many vehicles (planes, boats, cars) can be used to explore the land and complete the missions. It isn't ''quite'' a sandbox however: the interaction with the environment and NPCS is limited, there are no real side-missions and most of the landscape is unavailable if you don't progress in the plot. Rockstar would later take the ideas introduced here and refine them in ''VideoGame/GrandTheftAutoIII''. The rest is history.
!!This game has examples of the following tropes:
* AlternateHistory: The game starts out as this. The aliens attack in 1916 in the middle of UsefulNotes/WorldWarOne, and then slowly annihilate mankind by returning once every 25 years to consume entire countries.
* BagOfSpilling: You lose most of your weapons and items when entering a new time period.
* BrainInAJar: The Big Bad is the Alien Hivemind, a giant brain floating in a jar deep inside the Alien Comet.
* BugWar: The Bugs, which are of the ToServeMan variant. Since due to time travel, you're fighting with them over a hundred year period, every new generation of the bugs features new enemy units.
* ButWhatAboutTheAstronauts: The last humans in 2016 are on a space station orbiting Earth.
* CoolShades: The Goliath bugs in level 2.
* ColonyDrop: [[spoiler:With their invasion thwarted on four seperate occasions, the aliens decide to go for the KillEmAll solution by trying to crash their artificial comet into Earth. Adam thwarts them once again by disabling the engines before they can do so.]]
* TheDragon: The Man in the Black Suit. Later revealed to be [[spoiler: your Evil Twin]]. He becomes a DragonAscendant after [[spoiler:you kill the Hive Mind]].
* DummiedOut: The game changed genre quite a lot during development: It was first going to be a RPG, then a pure shooter before ending up in its current form. The completely different gameplay between the indoor and outdoor sections and the strange mapping of the landscape are relics of the different concepts. [[http://flickr.com/photos/mikedailly/sets/72157602060415175/ This image gallery]] uploaded by a former DMA employee show there was going to be levels set in Hawaii, Japan and Antarctica.
* EasyModeMockery: Good luck getting access to level four if you've played through the previous three on Easy mode.
* EventFlag: In the first section of Java, you are supposed to take a lift to get back to your starting point. After completing the primary objective, going to the lift will trigger a jelly alien on the local electricity generator even though it was fine a few seconds before.
* EvilEvolves: The Bugs invade Earth four times over a hundred-year-period, facing the time-traveling human super soldier Adam Drake five times. In each new time period their forces have mutated to become more developed and stronger than in previous eras despite their failure to harvest enough human DNA.
* EvilTwin: The Man in the Black Suit. [[spoiler:Revealed to be ''literally'' your evil twin at the end of the game. The invading aliens sampled a droplet of Adam's blood that was shed during the game's intro sequence, and used it to create a perfect copy of him]].
* FakeDifficulty: Getting stuck in ''any'' type of liquid will kill you in a matter of seconds, no exceptions. This is despite Adam being shown to have competent swimming skills. That lake over there? It may as well be filled with acid.
* FateWorseThanDeath: The poor Russian train conductor during Siberia 1 who had been exposed to a dose of the [[ZombieApocalypse zombie gas leak]]. He is seen leaning on the wall and sitting almost lifelessly on the floor of his home once you first meet him to get the train starting handle. Once Adam gets the train starting handle downstairs and tries to talk to the train conductor again before exiting, the conductor responds with nothing but groans. Instead of putting the poor man out of his misery (sadly, weapons could never be used indoors), Adam walks out of the conductor's home and leaves him to turn into one of the many zombies wandering throughout that area.
* GiantEnemyCrab: Your first major boss fight, no less.
* TheGreys: One of them is found in [[RoswellThatEndsWell Roswell]], purportedly the one who had his AlienAutopsy videotaped; he gives you the key to his flying saucer.
* HiveMind: Revealed to be a BrainInAJar during the game's final stages.
* ImplausibleDeniability: [[spoiler:Just before you kill the Hive Mind, it boasts that the aliens will return to consume the Earth's biosphere, and that they will kill you alongside themselves. At this point the aliens have been almost entirely destroyed, their plan to slam their comet into the Earth is twarthed, and are at the mercy of the humans. Just to drive the message home, Adam kills the brain by a mere kick to its container, which shatters it.]]
* InvisibleWall: Subverted in that the walls are visible DeflectorShields, and one of the goals is to destroy the generator that powers them. Doing so creates a crater that serves as the boss arena, making the walls unnecessary at that point.
* LockAndLoadMontage: The intro movie shows Adam suiting up while the aliens are invading the space station.
* MissionControl: Daisy and the robot who gives you instruction on the map.
* MoreDakka: Particularly noticeable during major boss battles in Alpha 1 and [[spoiler: the final stage]].
* NoEndorHolocaust: Even with Adam's help, it's likely that thousands of people died during each stage of the alien invasion. Luckily he time travels to the next level before we have to deal with it.
* OneWingedAngel: [[spoiler: The Man In Black uses the Hive Mind's inherited power to transform into Tomegatherion at the end of the game]].
* ReligiousAndMythologicalThemeNaming: All the bosses are named after mythological monsters and demons: Leviathan, Cerberus, Moloch, Beelzebub, and Tomegatherion.
* RegularlyScheduledEvil: When the aliens harvested humanity in the 20th century, they returned once every 25 years when their Comet homeworld is close enough.
** There's a lovely part in one of the America stages where you're in a military base the aliens are trying to terraform. A fast-closing gate blocks your progress at one point, the intended solution being to [[spoiler: get a can of nitro fuel and drive a jeep through the gate, the fuel speeding up the jeep just fast enough to make it]], but if you can't quite pull that off, take a nimble car onto the high ledges and you'll be able to jump a gap at the edge of the level. You are then able to drive in a flat area the designers clearly intended to be inaccessible. Result: Skip almost the entire level and drive straight to the boss.
** In the very first level, it's possible to get to the Alien Processor directly by using a motorcycle.
** In Java stage 4, if you keeping running towards the fence, you can glitch through it to get inside a harbor base without having to [[spoiler: Have the captain GoingDownWithTheShip to destroy the alien Barrier in a kamikaze attack]].
* SetRightWhatOnceWentWrong: Adam and Daisy travel back to in time to the first alien invasion, so they can prevent the harvest of the Earth from ever coming true.
** Justified in game. Adam can swim but doing so drains his health very quickly, as the armor he's wearing is too heavy to swim for long periods of time.
** Also applies to the Alpha tank in level 5, which will get stuck in what is most likely acid and take damage until it explodes... even though it's a ''hovercraft''.
* TimeMachine: The Alpha 1.
* ToServeMan: The aliens require human tissue to fuel their invasion force.
* UnexpectedGenreChange: The boss battles and [[spoiler:the entire last stage]] takes place in the Alpha 1 vehicle. You can get out of it during the bosses but doing so is an exercise in futility.
* VeryDefinitelyFinalDungeon: [[spoiler: The Alien Comet]].
* YourPrincessIsInAnotherCastle: [[spoiler: After Adam kicks the BrainInAJar, destroying it, your twin brother appears and transforms into the TrueFinalBoss]].
* ZombieApocalypse: The Siberia level.
