This question has probably already been asked, I am not sure how to check whether that has occured. If it has I apologize, but I would still appreciate an answer. I've had the game since it first came out, and I've already beaten it, however I need to find a walkthrough to unlock a few of the achievements I haven't gotten yet. Namely the locations of the trophy belts, the alien goo canasters and the mission logs or marine dairies or whatever they are called. So could someone please tell me where to find a walkthrough on the web? Thanks.
