A new patch for Call of Duty: Black Ops has been released to rectify a few issues.

Since its release late last year Call of Duty: Black Ops has frequently been patched to fix issues and Treyarch has just released a brand new patch. The title should download the patch once you load Mulitplayer and cannot be accessed in the Zombie mode. The full details of what the patch will rectify can be found below.

• Explosives are not visible through walls when using Hacker perk.
• Ninja perk is ineffective at times.
• Additional sound mix tuning for Ninja Pro users - increased ranges and volume of enemy footsteps, and removed player footstep sounds on concrete material types.
• Increased headshot multipliers for sniper rifles. Sniper rifles with suppressors equipped will be ensured one-shot kill headshots.
• Added a negative influencer to all spawn points to decrease the chances of spawning near an enemy. This will further improve spawning protection on top of previous updates.
• Previous Map Spamming � players are currently able to vote for the previously played map an unlimited number of times
• Incorrect Prestige Emblems appearing at certain levels
• Sending out text messages to massive groups can cause the game to freeze
• Demolition � getting a loss registered despite earning a win
• Some players experiencing crashes when viewing leaderboards with a high number of Allies
• Stuck in spawn spot in Cracked
• Voice Chat breaks up at times
• More reported cases of "unbound" controls
• Second Chance "invincible glitch"
• Several fixes that should improve performance/lag for host and client
