This new add on to Resident evil 5 is completely worth the 400 microsoft points. It tells the story of when Chris and Jill go to Spencer's mansion which they refer to a lot in the normal game. This add on is scaryer than the normal game and is made to be like the old resident evil's in which the stress build's up when you walk into a room waiting to see and enemey. I does include some new enemey's which do add to the thrilling affect of Resident Evil and recommend you buy it off the market place if you own Resident Evil 5.
