None.

Alien blood is seen when shot. Blue or purple in color.

Violence is present with primary guns and laser swords.

Hell, damn, bitch, ass, shit, bastard.

This contains the most language of any Halo game but is kept well within the PG-13 range. No strong vulgarity whatsoever neither in the original or anniversary edition.

Some mild language nothing severe usually language you would hear in T games

Uses of Motherfucker.

The humans and covenant often uses racist comments to one another, like "I heard that where you come from, you taste like chicken" "Take of the mask, you can't be that ugly" "Covenant motherfucker" "Demons" and the list goes on. This is used in battles, especially by the humans.

Staff Sergeant Johnson is mostly seen smoking a cigar and holding it several times.

Some cigars can be found in a room in Cairo Station during the Covenant's attack.

The flood may disturb younger players however 12 and above would more than likely not be offended. The flood are more disturbing in the Halo lore with books and animations however in the game it isn't went into as much. They're nowhere near as disturbing as the necromorphs from Dead Space, the zombies from Half Life or the disfigured creatures from the Silent Hill games.

The idea of The Covenant activating the rings to destroy all life in the galaxy may be frightening.

The Flood may appear scary to younger and even older players. The levels they're in are very dark and gritty.

In the Gravemind level intro cutscene, the Gravemind is made of decomposed flesh, with melted skulls on it, which is very unsettling. Regret is later shown in the cutscene for a short duration, with him being reanimated after his death in the Regret level, and his entire body attached to one of the Gravemind's tentacles. Very disturbing.
