Sacred 2 is an Action-RPG that was released in 2008 and is the follow-up for Sacred. However, as with most games, this game has long since been abandoned by it's developer, Asceron, considering that they dissolved in 2009 (A year after Sacred 2 was released). As a result, a lot of bugfixes and lost content was never realized or recovered... Until the community patch. This community patch does what it can to restore a lot of the content lost because of the typical rushed production schedules that games go through as well as tries to fix a lot of the gameplay bugs that are typically too small for developers to patch when a game is first released. Considering that Sacred 2 is not as moddable as the Elder Scrolls series, the Community Patch is basically as good as it gets to an official and conclusive content & bugfix mod outside additional weapons and graphical tweak mods.
In an odd twist, the only two ways that you can get this file is by registering to one of two modding sites. However, upon registering to one of the sites, the link that they provide merely goes to a file storage site that has no registration requirements. Therefore, I've saved everyone a step by just linking to the file itself (although registering for the site gets you a plethora of minor-to-moderate mods - Just don't expect the type of mods seen with Bethesda games). Enjoy.
