So... How real exactly does this get? The trailer shows a woman walking up to some guys house with an axe... What is meant when they say "eliminate a person"?
You won't really kill anybody, it's roleplay. This agency prevents and investigate on occult disasters, sometimes we have to effectively eliminate threats, and that can take the hardest of forms. Keep in mind though, that your character can die too.
For one, this should've been posted in the General part of the thread. Ongoing Mission threads are questions related to either a Client Mission or a Live Event. Secondly, no, you won't be asked to murder anyone. So far, we've had agents around the world travelling to major cities to do recon and take photos of transport assets for use in an escape route. We've had an agent go to a fast food restaurant in Portland and give them a password to receive pieces of information. We've had people across the globe go to public live-feed webcams to complete a mission. How "real" it gets also depends on your clearance level. If you're red, you won't get much apart from the in-game missions and an e-mail. The further clearance you are, the more interaction you have, so you might receive phone calls or packages in the mail. In short, you'll be asked to do things in the real-world, but nothing that will put you or any other person in danger.
As Dylan said with his words, it's a game before anything else, even if sometimes it looks real and very close to the real ambiant of those conspirational themes. It's immersion, no more.
