So much freezing and glitches it becomes unplayable over time they shouldn't have used the same engine because its an old engine and they keep adding more to it and it can't handle anymore. It freezes all the time, I haven't played it a single time without it freezing and me getting frustrated over having to restart the game every 15 mins when it freezes so I just quit and come back later. Not the best but the story is very interesting and graphics are amazing if they could fix the frequent glitches and freezes it would be an outstanding game but with these issues I can't play it without getting very angry
