A VERY generous two and a half stars. I see this series as more of an interactive sim than a fully fledged 'game'. On those merits I did enjoy it and the story did make me want to continue on without break. Its the gameplay where things start to fall apart though: The bullet sponge enemies and artificial difficulty make combat an absolute chore, especially when its wave after wave of enemies. Bullets feel like they're hitting steel instead of an organic object every time you shoot someone. The puzzles in this series really piss me off too, because its more about deciphering just what the fuck is meant by the notebook, instead of just trying to figure out for yourself. Well laid out visual cues from a better game like Portal 2 would have been preferred. So many instances where I just dont know where to go next, a heavy criticism I have over the entire series.
