If our only saving is the one of the end of the game where we are in the camp of Ceasar before speaking to the general, I have to begin again the game to get DLC??
Because once inside I cannot more stand go out again and if I speak to the general, the game is finished, then I'm blocked ??

I can just barely make out what your trying to say, but yes, you need to load a save from before the endgame to play the DLC. You do realize that you can save manually right? By yourself?

I did it, but my last save is before to speak with the general..

You'd think people would read the little posting before going to the battle which states that IT IS THE POINT OF NO RETURN, YOU SHOULD HAVE A MANUAL SAVE BEFORE GOING THERE, AND THAT YOU SHOULD DO EVERYTHING YOU WANT BEFORE COMING BACK SINCE YOU WILL NEVER RETURN FROM THE FINAL MISSION. Really, is reading so hard?
