Elysium is set in the Stargate Verse.This explains the ridiculous technology. At some point, the NID got their hands on a sarcophagus, and they reverse engineered it to invent the Med-Pod. Being the elitists that they are, they weren't interested in improving the lives of the common people, regardless of how much money they could make doing so. As a result, they built Elysium, obtaining financing by selling lots there complete with Med-Pods and the promise of nigh-immortality. It also doubled as a defense against alien attack- if any hostile aliens show up, it'll be the commoners on the surface taking the casualties, while Elysium simply avoids the problem by maneuvering away from Earth.
Elysium is set in the District-9 Verse.We didn't get nothing from the alien tech and the prawns are either still in South Africa or got picked up when their friends came back. In fact a retaliatory alien attack could have been the "ecological catastrophe" that turned Earth into a Crapsack World.
Kruger was once upon a time normal.How else do you explain him getting into such a position, where he can have access to weapons like he does? He used to be a logical agent for the government, but he had a head injury, which (like we saw in the movie) he healed from... Needless to say, he came back just a tad wrong. However, the change was really really subtle, so his superiors didn't catch on. After that one incident, it happened over and over and over and over again, leaving him the katana-crazy villain we saw in this movie.
Afrikaans culture Recycled IN SPACE!!District9 was an extended Van der Merwe joke. This was a total reconstruction of Jan Pierewiet. The next film is going to be... Kinders Van Die Wind! Or, Hex River. I dunno.
Elysium is set in the Mega Man universeSpecifically, in between Mega Man ZX and Mega Man Legends. In Mega Man Legends, Earth is covered in ruins of a high-tech organization that used to inhabit it but left for some reason. In Mega Man Legends 2, we find out about a distant world called Elysium, where humanity used to exist in peace with absurdly advanced technology, and that the citizens of Elysium were the descendents of the people that created the ruins. By this point, however, Elysium is uninhabited. In the Mega Man ZX games, the last series of Mega Man games before the time-skip to the Legends games, the line between humans and androids has begun to blur, as humans convert themselves into cyborgs and androids become increasingly human-like. It is also mentioned that they are creating a world called Elysium.
Elysium is in the Mass Effect UniverseDue to Max's actions, the quality of life on Earth is improved to the point where true rebuilding can begin and the slums are restored to full cities. A few years later, the first true missions to Mars are launched using Elysium, which is now a glorified Space Station as a launching point, and the Prothean relics are found. Then, the next is history.
