hey new recruit! Are you ready to join S.H.I.E.L.D's computer-based missions department? You'll be solving cases in and out of S.H.I.E.L.D purely on computers, and receiving notifications from other S.H.I.E.L.D agents. We have tight security around here, but if we're infiltrated, hacked, or otherwise, you and your teammates will be on the case. Got all that? Don't worry, your first email will be of more help than me. Well, come on then! THIS BOOK IS DISCONTINUED. DO NOT EXPECT AN UPDATE EVER.
