I havent beaten the Game yet , however it is pretty darn fun to Kill , at Will. Nobody is Off Limits , although you are penalized sometimes for popping the WRONG melon :) However with big maps , and great weapons , its worth it. The ONLY imporvement imaginable for this , imagine HITMAN meets true RPG Wow!! Other than that GREAT JOB
The main annoyance (and it's a pretty big one) in this game is the fact that you can't just don a disguise and freely explore. The enemy detection just seems a little too much. As a result, finding the right disguise becomes pivotal to almost every mission, and even with the right disguise, you will still be trying to mostly sneak around with that disguise on. This really takes away from the feeling of being a smart, tactical, hitman.
The maps aren't that big, and there aren't that many fun ways to dispatch an enemy unlike previous hitmans. Sometimes you also encounter glitches where the target stops walking in their usual path, and the effort you took to set up the ambush completely goes to waste.
Overall, there is a somewhat interesting story and characters, but in terms of the actual hitman style of gameplay that appealed to many fans, this title falls short due to the strange additional mechanics (instinct/enemy disguise detection) and lack of kill methods.
