Bad
I have played the game over a hundred times, i believe there is no bad language in halo wars.
Short answer: bad. In Halo: Reach the Elites (Sangheili) are fighting for the Covenant. This is rather confusing to many players as they were allied with the UNSC in previous Halo games, but keep in mind that Halo: Reach is set before even the first Halo game, Halo: Combat Evolved.

Well, honey, in most Halo games, you can usually find the option to censor bad words in the settings menu under "Content Filters" or "Language Filters." Just toggle that bad boy on, and you should be good to go without all the colorful language. Just remember, even with those filters on, there's no guarantee you won't still hear some colorful language from those pesky online players.
only in the last level of halo2 and all of the game in halo 3 :)
