The purpose of The Agency is to answer the question: "what can I do if I log on and I only have 45 minutes to play?" Or its variation "why should I log on as I only have 45 minutes free?"
It's also an answer to "OMG could we have something different in missions?!"
So, here comes The Agency.
Every 24 hours, you'll be able to visit The Agency and meet the Man Behind the Desk. He will offer you some new mission that will be soloable (some won't) and balanced to be doable in 30 minutes or so.
The Agency should be released in the very next months.
