Its about international criminals (bankrobbers?).
The world will be the Earth as we know it. Timesetting: 2011!
Everyone could be either a criminal with his own speciality. They could all met up later and form a team. (Or already be part of the team if they're in the RP from the start.)
Or you could be an agent from an international agency (CIA or Interpol or so)
Then your objective is to hunt down the team. The fun thing about that is that you'll have authorities in various police departments. Sometimes to do the right thing means you'll have to break the law though
Another option would be playing as a mercenary, hired by rich bank owners who want their money back + revenge on the team.
Multiple characters should be allowed, but preferably not on both sides of the law.
Hi-tech equipment is also allowed, but keep it realistic and not too hard to understand.
