Sacred:Sacred Vault
SacredVault is (so far) the only CodingCrew who does allowed tools for Sacred/UW . They have also done an unoffical Patch (2.29) which, at the moment, only works with the German Version of Sacred.
They have also started working on tools for Modding. Which is still under review by Ascaron for general release.
One more highlight is the Cheaters Nightmare Tool for the open Net of Sacred, which works with the german version of the game, and is, as yet, still untested on the International Version. It can directly filter out Cheaters and ban accounts on the gameserver.
Most of them participate at the betatests for Sacred, and are highly connected to Studio II.
SacredVault is not only for German speakers, with most of the members having good proficiency in English.
