We always enjoyed the choice of locations in the parent game, such as the cultists with the horrendous secret hidden in their basement. It was a step away from the traditional tactical shooter warehouses. The Stetchkov Syndicate takes that sense of style up a notch as you flit through a church rammed with recovering junkies in one level, then sweep into a rock club with a massive devil statue the next. Excellent.
Meatier story, more creative, twisted-up areas and less bugs; this extended tour of duty is worth signing up for.
