Overall the game is pretty good. Each map has so many different ways to take out a target and I think the story is very interesting. The levels are looking better than they have ever looked before. With each mastery unlock, comes a new item that will help with future play through's.
It's a sandbox game and when you enter a level, you have freedom of approach. You can go in stealthy, and move unseen through trespassing or hostile areas, you can acquire a disguise to blend in, or you can just fight your way to the target(s). Each level has so many challenges, some are time consuming, others are fun. There is contracts mode, escalations, elusive targets, and the main campaign, so this game is packed with content.
I recommend playing Hitman 3 in online mode to get the full experience. Each level has replay ability written all over it. I'm really impressed with the work that IO Interactive has done!
