Find the way to clear area around the first generator in Michigan Ave Reservoir level. Knock out all enemies without M&E. It's really hard cause level designers literally force you to use mark and execute feature and limit your stealth options.
Very nice. Do the NPCs talk russian or isn't there any voice over at all? I heard the russian version of SCDA, very nice job with the voices. Is there a way to get the russian text and voice packages for the previous Splinter Cell titles?
BTW: The problem in New Orleans was reported to the dev team, but there is no guarantee they will make a patch.
