A new update is now available on steam.

To recieve this update you will need to log into Steam, and it will automatically start downloading the patch providing you have set it so (default option is too download automatically).

1.2 update release notes:

* Added four additional multiplayer maps
* Added additional content for characters
While these are of no use to me personally ( I have no time for multiplayer games), it's still nice to see fresh content!
