As Corporate team seems to be of very likely interest, some notes on the megacorporations of the time of Red:
Arasaka: Japanese zaibatsu that is heavily involved with corporate security, arms manufacturing and maintains a standing army larger than many first world nations. Expect long hours, obligatory after-work binge drinking and to be ready to die for your corporate overlords in exchange for their undying loyality (or at least that is the image that Arasaka seeks to maintain).
Biotechnica: Californian biotech company focussing on genetic engineering, micobiology and bio-chemistry. They maintain a green image and resemble more an overgrown start-up run by scientists and bioengineers.
Continental Brands: American food and beverage company that not coincidentally has a red and white logo and not coincidentally has an important branch office in Atlanta. They run their food brands and franchises very aggressively and seek to discourage and undermine competitors, the urban gardening trend and other intruders into their captive market, with "mine" sometimes being meant literally.
Danger Girl: Small but upcomping Japanese-American private investigation and security company founded by a granddaughter of Arasaka Saburo, the old black-hearted patriarch of the zaibatsu of the same name. Danger Girl presents a cutesy, inoffensive and glamourous image.
Merril, Asukaga & Finch: A financial counseling and investment company from New York, MA&F moves a lot of money for its size and maintains some very powerful business relations. Their image is conservative, discrete and highly exclusive.
Militech: American arms and private military company grown out of the US defense industry. They maintain an All-American, patriotic image, but aren't all that squeaky clean under their propaganda, especially when it comes to undermining their main competitor Arasaka.
Network News 54: American news and media company. While it grew out of a reputation for tough, accurate, hard-hitting journalism, it has since long branched out into general entertainment.
Orbital Air: A French-Kenyan aerospace company controlling most of the passenger and cargo traffic between earth and space, and a good chunk of the orbital and lunar facilities. The recent uprising in the orbital colonies when the Highrider Confederation declared its independence has hurt their bottom line, and they seek to re-establish their grip on them.
Petrochem: Texan fuel company that has grown out of the petrol industry of its home state and gone with the times to slake the world's fuel thirst with CHOOH2, the alcohol-based replacement fuel. Despite this shift Petrochem still maintains a great number of oil fields producing polymeres and other petrol-based goods not as easily replaced, and is always eager to add some more, or to slap the greedy paws of some local government seeking control over their homeland resources.
Rocklin Augmentics: Texan cybernetics company with an All-American image of producing American and employing American, especially those who have been disadvantaged in the recent crisises.
Sovoil: This petrol company is what happens when ruthless Russian oligarchs of tomorrow plunder the USSR's state companies and their monopoly on natural resources. The company has been asleep at the wheel during the technological shift towards CHOOH2, but is now aggressively pushing into the market for replacement fuel and adjacent industries like aerospace after having consolidated their economic hold on the former USSR and its client states.
Trauma Team: The premier healthcare provider of North America, especially notorious for its armed, ruthless but very effective ambulance service for those who can afford it.
Ziggurat: A cyberspace company from very Night City itself that controls much of the backbone and physical infrastructure of the modern internet. It maintains an image of unorthodox avantgarde out-of-the-box thinking of a plucky tech start-up.
Zhirafa Technical Manufacturing: This Russian robotics company is especially involved in the development and application of drones and robots, especially the industrial variety. Their sudden rise is a bit of a mystery, which many attribute to their connections to the Russian mob.
