The downside is that you have to be a Gamespot member to get these, but the signing on process is free, so there isn't too much to whinge about. The inclusion of pictures is a nice touch, but in order to keep the file size down they are VERY low quality. If you are after a walkthrough that doesn't give too much away when it comes to every little step, then this will probably please you. The layout of the text is confusing with no numbering system or bullets etc. Everything is crammed together, making navigation confusing.
Pictures take too long to load.
Bad shortcut coding. No actual in-game screenshots despite the amount of pictures. Many important navigational instructions are left out. No explanation for sludge pool. Doesn't tell you where the red corridor is or how to get there.
