I'd like to share this save, which as been the result of an exchange with the user NATAS, you only have to replay the sequence 1-1 and achieve the secondary goal of not being detected and the achievement of get 100% sync on the story missions will pop up. Sorry, I left this one (seq 1-1) to the end thinking that would be the easier and didn't remember about the intro video. And wasn't the shorter, sorry about that again. Original save game credit to NATAS, I've replayed those sequences that weren't at 100% until just one left for the achievement, any other thing was made by him.
