As for me, having known 1 Halo PC and Halo 3 on Xbox 360 I think this is best done in the series. More nervous, with harder and more intelligent enemies, and with very impressive graphics for a machine as old as 360. 343 Industries has taken over from Bungie successfully, I think.
For those who would pose the question of the language of the game: menus and subtitles are in French.
Only the voices are in English, but it does not bother me (little dialogue during the phases of play, though much less than for a GTA for example).
