A day later than expected, de_nuke is now available for Counter-Strike: Source. It is the first map to include High Dynamic Range lighting, which is also used in Half-Life 2: Lost Coast and Day of Defeat: Source. The update available through Steam does not just include the map, it also offers bug fixes and bot changes. Here are some of those bug fixes

- The Bomb (C4) can no longer be planted on breakables, movable physics props, or other players
- Fixed problem where players were not always "grabbing onto" ladders that were approached from above
- Crouching while traversing a ladder reduces the player's speed (matches CS 1.6 behavior)
- Improved door logic to prevent doors from opening into the player using them
- Bomb-related sounds play for everyone correctly now (not just the bomb-planter)
- Fixed incorrect bullet penetration calculation through concrete+grate materials
- Fixed changeteam exploit
- Fixed apparent lockup/hang due to the disconnect dialog showing up over the quit menu and hiding it
