Yeah I'm playing on 360 and it crashes all the time, it seems the 360 version crashes more often but the PS3 versions suffers from more framerate issues and some audio glitching..It's a shame I really like this game the story for this game and some of the character work but the build quality is not to the same standard as the Rocksteady games. It feels like it needed an extra month to iron out bugs and work on the stability.
It really bothers me that Sam seems to walk around with his weapon out all the time, can you holster your weapon with down on the d-pad like in conviction? I know its kind of silly to find this annoying but I would really appreciate an answer before I pick this up. Thanks.
