Ubisoft has detailed the long list of changes made to FarCry 2 on 360 via a fairly hefty patch today.
Most notable is the fixing of an issue surrounding saved games becoming corrupted, although if you've already encountered the problem you won't be able to recover your data; you'll have to start again. Soz.

Many of the new features were requested by members of the community and we would like to thanks everyone for taking the time to communicate with us, we hope you will enjoy the improvements.
* We are very aware of the problems some people have been experiencing and have been doing everything within our powers to resolve these issues as quickly as possible. We found out during our testing that several elements could cause an issue with the same consequences and therefore prevent certain players to finish the game. We have been able to provide solutions that prevent those corruption problems in most cases and we haven't encountered any problems now. We apologize wholeheartedly for the inconvenience that this matter has caused to some owners of the game.
** In answer to a growing demand we have developed a tool that enable us to mark user's created maps as ranked. You should already find a selection of those maps thanks to some of our active community members.
