The concept of an expansion is, that it builds on the original game and is essentially the same as before (but most people would like to see a few new things as well.)
On this basis; the pace is fast, retains the atmospheric quality and addictive gameplay of the original game. The storyline is a bit vague compared to its predecessor's but nevertheless the intoduction of the 'nightstalkers' makes a worthy foe. They are more difficult to kill and very agile in combat. The final battle is definately a challenge, if not a little predictable. I hope their is more to come, this will definately entertain a die-hard fear-fan.
Graphically, it is not up there with titles such as Crysis but bear in mind this game was produced on pre-Crysis technology and in its time, it was percieved as good. It will still make you jump and retains the intense moments of suspence and anticipation prior to entering those seemingly innocent and emply rooms for a big dynamic fast paced fire-fights. Fully endoresed and recommended in my view.
The new weapons are a great addition, and necessary to overcome the well equipped enemy forces.
The reviews that slate this game for being 'more of the same,' what did you expect? Its an expansion pack! If you want a game with a totally new concept, then buy a new game!!
