Just started and gotta note this is very vague. This is what I get in the very beginning of the game:
Upon stumbling over the first few enemies, continue until you reach the guard you need to either distract or kill with your rifle. It is your choice what to do. I strongly recommend to not harm him for a better rating.
How, would be nice. Instead of a vague description of what needs to be done.
I know the author (edited a different WT for him before) and have sent a PM to ask if I can edit this one. I'll add more detail and some pictures to hopefully make it a little easier to use.
