The first half is one of a greatest games of all time; the second half is unfinished garbage that knocks a full star off. Worth playing for the S-tier first half.
Overly ambitious in its design resulting in major cuts having to be made to get it out the door. As a result the story is obviously truncated as is the level design. The ending also makes no sense. The presentation and atmosphere saves this.
Fairly solid foundation ruined by the need to be a live service. It's a shame because the characterization of the main campaign characters is all really good.
