Universal Master Code [updated] -

In the not-too-distant future, a team of brilliant engineers at a tech firm called "OmniCorp" had been working on a top-secret project to create a universal master code. The goal was to develop a single code that could be used to access and control any device, system, or platform, regardless of the manufacturer or operating system.
