I've beaten the level once, but some abilities are not at 100%, and now I want to continue to improve them. However, when I choose to continue playing, it starts at the last save. When I select a chapter, the ability also reverts to the progress I made when I saved the chapter. So what should I do to get my abilities to 100%?...

So how hard is Survival? I'm pretty decent at stealth games and the first level on S was fine - any reloads would be on account of new game mechanics. However, I'm a bit put off by not being able to change without restarting if it is too hard.

Ask questions about the walkthrough and any other questions here.

It says it double effectiveness of drugs, but the second wind drug still only provides 2 concentration. :(
