The error described in the other reviews I can only confirm. Partial running the game in slow motion, a state which is otherwise known only from PCs to slow CPUs and graphics cards, but not from a game console. The camera comes partially in comic angles to stand, so you can see what is behind the wall, in front of you stand. Opponents running against walls and do not react to the player. You really get the feeling of playing a beta version.
My dealer were known to demand such problems only from the PC version, and he pushed the problems on my console, with all other games run perfectly. An exchange is according to traders only if the manufacturer gives a deficiency, which has not happened until now.
I guess first wait and see if possibly get updated versions or something like that, otherwise you throw your money out the window.
Hope this review has helped you. MfG
