New Game + (Play through number 3)I'm just curious, can you only play through this game twice using the same characters?? A friend and I made it all the way through the game twice using the same characters. After beating the game the first time, we had the option to go through the game again. When we beat the game for the second time, I never saw the option to play through a third time, it just let's us walk around going to any area and kill enemies, but there are no more objectives to complete. Can we play through the game a third time with these characters or do I have to start over with new characters to be able to do the objectives?? Any info on this would be greatly appreciated.
