The downsize in scale has effected how the map plays. I felt that I was being buffeted about through some of corridors and even in the outdoor areas there isn't much room for movement. Item placement is fairly similar to the original as I recollect, so if you've played that you should no problems here getting up to speed. If you haven't, it'll be a bit disorientating at first as you get your bearings since some sections look similar. The map does spread out a bit so a few peeps are needed to make it worthwhile. Teamplay would most likely work given the item placement and tight layout.
