PC x is a hacker with the NSA and PC y is a counterpart in the Chinese cyberwarfare program. Any two rival nations with enough technology to have a cyberwarfare program will do as replacements (Israel/Palestine, India/Pakistan, etc) and even petty warlords can afford one or two pretty good geeks on their private army nowadays. The players should be accepting of the matchup though.

Anyway they are long time opponents. They know all of each other's handles and have been opponents on many clashes in the web. They have yet to see each other's faces and are a mystery to each other.

Somehow they come across evidence that aliens are on Earth with sinister intentions. They team up without the knowledge of their respective agencies to partner against the mutual threat to both countries.

This story can grow bigger until it becomes a whole space opera epic. It might end up with Earth propelled into an intersteller universe as a new kid on the block and a Terran federation having to be formed. More pcs can be added on, and there can be several generations of pcs some children of previous ones.
