Really good game, when it's not forcing you to do stealth (which the system is not great for), not properly informing you when you are unable to leave the upcoming mission, not letting you consistently find cover on items that look like you could, not warning you before defense sections end in cutscenes that will not let you re-gather turrets (a limited resource), or introducing instant-kill mechanics, forcing you to replay annoying sections.

Other than all that, it's really good. Those elements are introduced more as the game goes on, alongside bugs (which were also more prevalent as I went through the game).
