Setting and plot > gameplay, but cool overall.
The story is interesting and great, but I can't spoil it so that's all i can say.
And the gameplay is the usual fps mechanics, nothing very relevant.
Gameplay wise I was only amazed at Elizabeth's AI, she doesn't get in the way, she throws you ammo and health, she doesn't repeat herself with one liners, her facial expression is constantly changing in a believable way and she walks and runs in front of you, instead of just following your trail.
It's basically a new level on companion AI.
In general , as a movie game, it's pretty great, except for one thing in the plot that makes 0 sense, but you kind of forget it exists by the end.
Also, the fact that enemies don't die from a single bullet to the head is kind of nonsensical, if you're gonna make it like that at least give helmets to all of them.
But that's nit picky.
