Io-Interactive has announced that HITMAN will receive a new, tougher difficulty setting as part of the free January Update with the disc launch on January 31.
Professional Difficulty Level will offer a tougher challenge for players. With new game features, a separate mastery track with unique rewards, tweaked game mechanics and new AI behavior that combine to create an entirely new experience for all players.
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. To unlock Professional Difficulty Level players will need to reach Mastery Level 20 for each location and there are separate leaderboards between difficulty levels. Professional Difficulty Level will be available for all main Story missions only, excluding Prologue.
