No it is not timed. So you'll see all the content. The only place where time is a factor is the Island (Chapter 1), but you can revisit that as many times as you want. In chapter 3 there are a few missables, so if you are a completionist, use the walkthrough for that.Not played this series since giving up around chapter 2. Gonna start from scratch but I can't remember, is this game timed, as in does it eventually get to a point where it wants you to start the next chapter and you end up not seeing all content?
