Finding the right balance in any game is always a challenge. No-one wants to play a game that is just far to easy, although at the same time no-one wants to play a game that feels like it is just impossible. Transcribed by Kotaku, from a preview build of the game, it appears that there will be a difficulty level to suit all abilities.

Enhanced: Easy - Supreme training and a physique enhanced beyond ordinary human capacity mean that your enemies are no match for you. By cunning or by brute force, you are unstoppable.

• Players can activate additional checkpoints
• Instinct regenerates
• Instinct will provide hints
• Enemies react more slowly than normal

Enhanced: Medium - You can rely on Agent 47's superior training and instinct. Remaining completely unnoticed can be a challenge, but you can always rely on your guns to get you out of trouble.

• Players can activate additional checkpoints
• Instinct does not regenerate
• Instinct will provide hints
• Normal enemy presence with normal reaction times

Professional: Hard - You like a challenge and your enemies will provide you with just that. They will be more numerous and with faster reactions. Evading your enemies will be difficult and you must strike with flawless timing.

• Players can activate additional checkpoints
• Instinct depletes when used and does not regenerate
• No instinct hints
• Additional enemies with improved reaction time

Professional: Expert - You fight for every inch of progress, often without firing a single bullet. You don't rely on any help and accept trying many times before reaching your target...and perfection.

• No player-activated checkpoints
• Instinct depletes when used and does not regenerate
• No instinct hints
• Maximum number of enemies with fastest reaction

Professional: Purist - This is a challenge for a true perfectionist. You know every rule, every detail, and all environments by heart. Even then you will die trying.

• No Help
• No guides
• No Interface
