Does anyone know what the bonus objective is for level 10? I have beaten this level many times but can not find any bonus objectives. First I thought it was to find the fab lab without tripping any alarms, didn't work. I thought it might be to overhear the conversation in the fab. lab but that wasn't it either. I have found all intel and have been able to eliminate all exterior troops without raising an alarm or being seen.
In one of the builiding to the right of the entrance towards the back there is a room up a catwalk-ramp that looks kinda like a office. In it there is a safe in the wall. You need to supply c4 and you blow the safe open. In the safe there is documents that you grab and you got it. I needed to ask a friend about this too.
You have to make sure that you take C4 with you at the start of the mission. It's a stupid bonus objective, that doesn't have any benefit except for a little cinematic clip and to boost up your completion percentage.
