Borderlands dlc compatable?

Does the description of the giveaway said its for German language?

look at the gift in your inventory, if it says its region restricted then its Germany only.

To the cdr mobile!

a few minutes later Apparently the german version should work, however you'll have to deal with the low violence cut.

It should be compatible, just that it may not work as intended.

I believe it's not compatible. If I remember correctly you'll get an error message in Borderlands saying the base game and the DLC versions don't match. But if you activate the gift and it doesn't work, Steam Support should be able to change it to the correct version.

German restricted games or DLCs usually take away the violence from the game, but they are usually compatible as far as I know... However, so that you are sure, just ask somebody with the German DLC
