An update for Counter-Strike: Global Offensive was released tonight. Among the many changes, changes have been made to the way the C4 is planted in maps. It now features an audible tune that everyone can hear but only the player planting will be able to hear the code typing sounds. This allows for the possibility of fake planting, just as CTs can fake diffuse.

There are more changes to the sound design, fixes to the maps, UI, and more.

Changelog for CS:GO for November 6, 2013

GAMEPLAY
- Changed C4 planting sounds based on pro feedback. When planting the bomb, it plays an initialization sound that everyone can hear, but ONLY the player planting will hear the code typing sounds. This makes fake planting possible (similar to fake diffusing as a CT).

- All items now follow the same pick up sound rules (grenades, C4, weapons, defuse kits, etc):
-- If a player picks up an item while running, it plays a pickup sound that everyone can hear.
-- If a player picks up an item while moving silently, it plays a subtle pickup sound to ONLY the player picking it up.
- Weapons, grenades, and remaining money are now displayed as icons above player heads during freezetime. (Thanks R-arcHoniC)
- Fixed overhead teammate arrows not showing up in some cases.
- Fixed automatic observer target selection failing to find a controllable bot when a player was killed.
