The patch itself will be available this Thursday, 29th September, and will be free to all PC users. The Xbox 360 version of the game will include all these changes too.
"Arena - is a new gameplay mode that is separate from the main adventure and narrative of The Witcher 2. In this mode, Geralt of Rivia duels a variety of foes to the death in a gladiatorial arena located in an unnamed town somewhere in the Northern Kingdoms. In addition to winning gold and valuable items, players also receive points for their wins. They can then post their point totals on-line to compare their achievements against those of other blood sport enthusiasts around the world. Geralt can encounter both foes and allies in the arena. He can recruit the latter for a fee to assist him during his most challenging clashes. To post your point totals to the forum, you must be registered and have a forum account! Register and establish your account directly through the game launcher or go to www.thewitcher.com. You can then log in to your account via the launcher.
IMPORTANT: Players using mods to alter their character attributes and statistics will not be able to post their point totals from the arena to the server. This is a necessary precaution to prevent any attempts at distorting competition or misrepresenting player achievements.
Tutorial - The game tutorial takes the form of a brief adventure during which players learn how to use a range of game mechanics and functionalities. Assuming the role of game protagonist Geralt of Rivia, players save a wounded knight named Bolton of Ironford while learning game controls as well as the basics of combat and alchemy. This transpires step by step as the tutorial guides players through a series of minor missions. Upon completion, based on demonstrated abilities, the tutorial recommends the difficulty level which the player should choose in embarking on the main adventure of The Witcher 2.
Dark Difficulty - The "Dark" difficulty setting is the most demanding difficulty level in gameplay terms. Under this setting, each and every foe represents a significant challenge. In addition to raising the difficulty bar, the module includes several new sets of equipment/items that are linked through a dark legend detailed in the Journal. Once all their components have been collected and donned, the Blasphemer's, Oathbreaker's and Kinslayer's outfits provide great advantages in combat. The swords included in the outfits strip opponents of Vitality while supplementing the witcher's. However, given that they are cursed, the swords provide no benefit and harm Geralt by sapping him of Vitality as long as the outfits to which they belong remain incomplete."
Version 2.0 Corrections/Amendments
Corrections and improvements to combat:
1. Numerous improvements have been made in the targeting system.
2. Parrying is now unlimited (even when Vigor is completely depleted), though parries no longer cancel all damage (maximum 50% reduction once the relevant ability has been acquired).
3. Responsiveness of game controls has been improved. This includes but is not limited to casting Signs, parrying, and attacking immediately after evading an opponent‟s assault.
4. Geralt's attacks are no longer interrupted by attacking opponents. Attacks are now contiguous and foes cannot interrupt Geralt's attacks by landing a blow.
5. Assorted fixes now prevent opponents from incessantly attacking Geralt after he has been knocked down. Geralt can no longer be knocked down repeatedly in quick succession. Also, he rises quickly while evading subsequent attacks.
6. Geralt no longer attacks opponents located behind other opponents positioned nearer to him.
7. The target locking system has been improved. Preference is now given to previously highlighted targets.
8. Target selection has been improved. Priority is now given to foes affected by a critical effect facilitating the completion of a finishing move.

10. Attacks can now be continued even when a key controlling Geralt's movement (e.g. W, S, A, D) is depressed.
11. Attacks can now be continued if the attack key is depressed immediately after the final strike of an attack animation sequence.
12. Geralt can now pivot 180 degrees immediately after completing an attack.
