Call of Duty: Black Ops has just received a brand new patch on the PC platform, taking it to version 1.09 and is now available for download via Valve's Steam digital distribution service.

Call of Duty: Black Ops has broken sales records and is currently getting ready to receive the Escalation DLC pack on the PC and PlayStation 3 platforms, after the map pack was released at the beginning of the month for the Xbox 360.

In preparation for the DLC's release next week, Treyarch, the developer of Black Ops, has just announced that update 1.09 for the game is now available for download through Steam.

What's more, Josh Olin, the community manager of Treyarch, confirmed on his Twitter account that the PC mod tools for Black Ops are still on schedule to be released next week, before the end of this month, so users can expect more details about the mod tools in the following days.

Until then, check out the main changes in Call of Duty: Black Ops PC patch 1.09 below.
