I've gotten to ch.03 and I'm really enjoying it. The shooting mechanics are solid but what makes combat huge amounts of fun is the feedback from shooting the enemies .... well to quote Eurogamer.
but the shearing metal and scattering components of Binary Domain's opponents is intensely satisfying
And that's true!
Now this game is definitely trying to imitate Western shooters but it's quite obviously Japanese made. You'll have the borderline angry black guy who uses "aight" repeatedly and you have to wonder what the fuck these guys were thinking. But on the other hand some of the set-pieces and bosses are amazing. The combat is hugely satisfying and the dialogue of the characters are interesting and fun (and since you can answer differently the dialogues changes).
At set intersections you can choose which characters you want with you and the dialogue changes depending on your choice. In addition, the routes you take during the mission are supposed to change but I haven't seen that happen so far. (Also, I don't know if the game has different endings, I haven't checked). So far I've experienced a couple of short cutscenes and one that was genuinely shocking (due to how brutal it was) so the story has some interesting things to say for itself.
If you're interested in a "odd" game then go for it. That's why I bought it.
