FPS fanatics can do much, much better than this, even on consoles.
Western FPS fanatics will have to keep waiting. There hasn't been a great Western FPS since Outlaws, and this is just another in the long stream of mediocre ones.
Deaf and Hard of Hearing gamers will be fine, as the game is completely subtitled, and has no important audio cues.
