Cutting edge technology does not a great game make. This game is proof.The graphics are beautiful, which accounts for the extra star for the overall rating. If you are a Tomb Raider fan, you will absolutely hate this game, as I do. The controls, the plot, and the movements are maddening, boring and confusing, respectively. Eidos could plug Tomb Raider 1 into this engine and have a much more interesting game.Maxim magazine gave this game 5 stars. A good reason to ignore Maxim's ratings.
Answer:
Negative
