Hitman is releasing on January 31st in a full season disc version. To accompany this release, Io-Interactive is updating the game with another difficulty setting, Professional mode, along with some gameplay changes and additional rewards. Here’s the official description:
The new difficulty level introduces strict item rules so players will be noticed carrying suspicious items, disguises that can be ruined depending how you take out the NPC wearing them, new security camera rules, limited save games and a whole lot more. Everything needed to challenge even the top players.
