Body Harvest
Body Harvest is an action-adventure video game for the Nintendo 64 video game console, developed by DMA Design. It was intended to be a Nintendo 64 launch title, but was delayed due to its original publisher, Nintendo, having issues with the game's violent themes, and eventual dropping of the title, leaving DMA to find a new publisher. It was eventually published by Midway Games and Gremlin Interactive in 1998. In "Body Harvest", players assume the role of a genetically engineered soldier, Adam Drake, who must investigate and eliminate an alien attack force that has been returning  once every 25 years to "harvest" the human population of Earth for their organic material. Being in possession of a time travel device, Drake must return to the past and do battle in five areas over a 100-year period that covers World War I-era Greece, Java in the 1940s, the United States in the 1960s, Siberia in the 1990s, and the near future (2016). The game is non-linear, as players can go anywhere and do anything within the limits of the game's boundaries. Plot. The opening text tells of how an alien force has harvested the  population of Earth over a 100-year time period. Every 25 years they would land and imprison whole areas in shields that prevented anyone from leaving and any outside help getting in. The aliens would harvest the population of the area within a time limit of one day before moving on to another area. After repeating this several times they would teleport back to their homeworld, an artificially created comet, before returning exactly 25 years later as it has completed its orbit around the nearby star systems back to earth. Greece was the first targeted area in 1916, southern Spain  was second, eastern Canada was third, and the south island of Japan was fourth. In 1941 the first targeted area was Java. In 1966 it was the U.S. (presumably somewhere in the southwest in between Nevada and Arizona) and finally in 1991 it was Siberia. The player only has to stop the aliens in the first area that they target in order to save every future targeted area of that time period. The opening cutscene shows Station Omega, an orbital space station containing Earth's last survivors. The year is 2016 and the aliens have returned to destroy the last  remnant of the human race. The aliens attack and board Station Omega, chasing Adam Drake, the game's only playable character, through the corridors. Even though Adam defeats the initial invaders he is wounded in the process. He is ready to board Alpha I, the time traveling vehicle developed at Station Omega, when more aliens appear and try to force their way into the boarding chamber. The monitors show his colleague, Daisy Hernandez, telling Adam to get into the Alpha I without letting the aliens gain access to it. As the aliens force the door open, Adam dives through the  air lock and fires a single shot into the control panel; this closes the door and prevents the aliens from pursuing him further. As they escape the station in the Alpha I, they are pursued by Alien fighter craft, but open up a time portal and escape. Meanwhile, back on Station Omega, an Alien is shown holding a drop of Adam's blood and eyes it strangely. This is a subtle hint as to where Adam's nemesis, Tomegatherion, is cloned from. Gameplay. Each level in "Body Harvest" requires the player to stop the aliens from slaughtering everyone in the  shield area. The player will navigate the map, often coming across towns where aliens will teleport in to attack the town and harvest civilians. Aliens will also warp in frequently to attack the player and can appear from the land, air or sea. Generally, gameplay consists of completing a series of missions. Many of these are very basic, e.g. reach a certain area, but others can be more complicated and require careful thought and skill. Once the player completes a mission they are prompted to check the map to find out what the next mission is. There is a meter  at the bottom of the screen that represents civilian casualties. If too many civilians die for any reason (including friendly-fire), the aliens will destroy the area and the mission will have failed. Generally, only Harvester aliens deliberately kill civilians, however the player must be careful not to shoot or run down any civilians in the process of rescuing them. The player must react to Harvester Waves quickly, as if the aliens manage to harvest 8 humans in a single wave they will create an extremely dangerous 'Mutant' creature, which immediately attacks the player regardless of location. There are also  several optional missions that require saving people from the aliens, and although one can fail these missions and still progress through the game, doing so will result in significant human casualties. The use of vehicles is a key aspect of this game. Vehicles provide significant protection from alien attacks and allow the player to travel at a far greater speed than on foot. Adam can still fire most weapons from within a vehicle, although many vehicles are equipped with powerful weapons of their own. Vehicles take damage independently of Adam and can be repaired with health pickups spawned by defeating  larger aliens. Specific vehicles are often required to advance - for example, boats allow travel over bodies of water, while planes and helicopters allow travel through the air. Each vehicle has a unique combination of top speed, armor and fuel capacity, inviting players to consider their options carefully. Vehicles range from mundane civilian forms of transport to powerful military hardware - the player will pilot tanks, armored cars and aircraft as frequently as cars, trucks and motorcycles. 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. The buildings also have Ammunition pickups and fuel cans (of which one will refuel a vehicle once). 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. The eventual goal of each level is to destroy the Shield Generator to remove the shield that surrounds the region. To do this, the player must first destroy a number of Alien Processors, which act as sub-bosses. Defeating an Alien Processor opens a gateway to the next area and allows the player to save their progress. Once the Shield Generator itself has been destroyed, the player immediately faces that level's boss. Once the boss is defeated, the player travels forward in time and to the next level. Development. "Body Harvest" was  one of 13 games demoed at the Nintendo 64's unveiling at the 1995 Shoshinkai show, though it was not in playable form and was described by journalists as one of the most incomplete of the 13 games. The development team were very enthusiastic about the Nintendo 64 as a development platform. Project leader John Whyte commented, "It's been really well designed and we haven't even scratched the surface. It's scary. The drawing chip is a masterpiece of engineering. There are no hassles for developers compared to other systems. You don't have to worry about clipping . It just handles it." In contrast to DMA Design's previous publisher, Psygnosis, who showed minimal interest in the development of their games, Nintendo frequently directed the development team to make major changes to "Body Harvest"s gameplay and visual style. The language barrier between the Japanese publisher and British developer added to the difficulty of implementing these changes, as the developers sometimes struggled to understand what Nintendo wanted from them; Whyte cited as an example a message in which Nintendo told them to make the graphics "more materialistic." DMA Design's head, David Jones, described their relationship with Nintendo: Reception . "Next Generation" reviewed the game, rating it four stars out of five, and stated that "Although not as clever or polished as DMA's own "Space Station: Silicon Valley", "Body Harvest" is an unsettling and thoroughly enjoyable game with lots of original and fun features." The game received "average" reviews according to the review aggregation website Metacritic.
