You are a witcher, a mutant. The sooner you accept this, the better. People will seek you out for your skills, but you must know to disappear when your presence is no longer desired. You are unique, different. This puts you in the same precarious position as non-humans who find themselves impaled or hanging from nearby trees. That they exist and are different triggers resentment, animosity and hatred among common folk, who will use any pretext to show them their proper place. How is it then that witchers, while equally non-human and different, do not share the fate of these poor devils? The answer is twofold.
First, relatively few of you walk this earth. Therefore, one is far more likely to encounter an elf than a monster-slayer such as yourself. And second, you possess a couple of rather forceful deterrents, a solid sword and a simple set of life rules.

Your blades are your lifeline. It's therefore unsurprising that your ability to wield them is renowned, or that very few are keen or even willing to risk their lives by engaging you in combat. Still, your prowess has not led to arrogance. Neither do you revert to force when it isn't necessary. As long as even a small possibility remains of resolving a conflict by other means, you sheathe your sword rather than tempt fate. However, you are unrelenting and without remorse when you must fight. You're no saint, and not out to save the world. Ultimately, you simply want to survive while remaining true to your profession.

The Witcher 2 version 2.0 enhancements and features are:

New Tutorial System - New, more comprehensive tutorial is designed as a separate part of the game and takes place in the Kingdom of Keadwen. New Tutorial System gradually explains all gameplay mechanics, from very basic to the most sophisticated systems. The Tutorial ensures that start of the game for everyone will be a pleasureable experience without too steep a learning curve.
Special "Dark" difficulty setting - A new, intensely challenging difficulty setting that provides the ultimate challenge for players. On the "Dark" setting, The Witcher 2 is nearly as difficult as "Insane," but allows players to save the game. It also provides a completely new set of dark-themed gear with very high stats. "Dark" mode also includes other special elements related to the "dark" theme. This setting is yet another reason to play the game again for those seeking new Witcher challenges.

• New items in the "Dark" setting:
• 3 new sets of dark armor (light, medium, and heavy)
• 6 new dark swords (3 silver, 3 steel)
• Other "Dark" themes/elements in the game...

Completely new, arcade-style Arena Mode. Infinitely replayable and progressively more challenging, Arena Mode lets you hone your combat style and techniques against all the different opponents from the game as well as a new monster type, the Werewolf. Dispatch wave upon wave of increasingly more difficult enemies, earning awards that you can use to upgrade abilities, weapons and armor, and to test alchemy. Hirelings can also assist you in battle for a price. Combat waves will continue until your character is defeated, when you'll see a statistical summary of results. Players can share their results with their friends by uploading this summary to the forums or to Facebook.

Arena Mode includes:

• New location - forgotten stronghold in the Kingdom of Keadwen
• Dynamic, responsive audience reacting to the events
• A new monster type, Werewolf
• 30 different waves of enemies, looped with increasing levels of difficulty
