Treyarch have launched fixes for the Zombies and Multiplayer modes for the 360 and PS3 versions of Call of Duty: Black Ops.
Released last night, the update should sort out “several” unspecified Zombies exploits, and fix the annoying bugs that let players get outside of the designated map boundaries on Nuketown and Kowloon in multiplayer. It also adds a team deathmatch exclusive Mercenary playlist, and disables split-screen play in Mercenary playlists.
Black Ops is a game that is so popular that glitches will always be discovered and regularly exploited, so fingers crossed there will be many more fixes to come in the future.
