The stechkov syndicate has just been released online and should be hitting store shelves during this week! But seeing as they do fishy stuff (the death of Swat 4 Urban Strike - what was suppose to be the real Swat 4 that got canned for unknown reasons) I preordered mine to get one of the first copies!
7 new levels, new cammos, new weapons can't go wrong for $20 bucks. For us Swat guys that don't know you can add new weapons and maps to swat 4 from the 10-david.com website!
