Megacorp is an unplayable team in Sub Rosa which serves as a key source of missions for players. With a large central office in the middle of the city, it's the most notable company, with a fleet of limos and offices staffed by NPCs. The offices and limos hold floppy disks for players to submit to their own companies for profit.
The disks are always located in a gray building with a single pillar at the door, past several NPCs with guns that shoot at all players, on a table in the 3rd floor corner above the door, or are held by the driver of a limo with 1 or 3 bodyguards, also armed.
Megacorp's central office is also a prime landmark and excellent source of bungee jumping.
