This patches provides the following improvements:

- Players using the Russian language will no longer crash as soon as they use the sniper rifle.
- Various issues that have been seen on specific configurations that caused the game to not be able to start up at all have been addressed.
- Problems with the Sniper Challenge Unlocks not carrying over into Hitman: Absolution have been addressed. On first starting the patched game you will receive your unlocks.
o Note that North American users that have been provided the Sniper Challenge by Gamestop will need a separate unlock key in addition to this. Gamestop can provide these.
- Problems with negative level-scores have been fixed. Newly accomplished positive scores will be needed to erase your incorrectly remembered negative scores.
- A problem with keyboard and mouse controls where users would accidentally melee attack a person next to them when they intended to throw an item has been addressed.
- Legal and Intro movies can now be skipped immediately on startup after the game, on all launches but the very first on a machine.
- DirectX 10 hardware can now enable the simplest version of the Depth Of Field effect.
- Problems with audio occasionally being muted after ALT-TAB have been fixed.
- Various localization fixes.
- Miscellaneous other stability and general improvements based on crashes we have seen coming in.
