Note that Serious Sam 3: BFE is more darker and adult than it's predecessors despite some humor thrown in.
The Witch Harpy, a in-game enemy, is disguised as a woman with bare breasts, but it's merely a tool to distract it's prey. Fortunately, mods can censor the nudity by adding clothing to the sensitive parts.

The trademark Serious Sam violence is present; from enemies being shot, crushed and blown up with graphic and gory results. Blood and gore will splatter on walls and the floor, sometimes make a pool on the ground. Eventually the enemy's corpse will disintegrate, leaving a pile of ash.
A new feature allows Sam to melee kill his foes with examples like breaking their necks, but also more bloodier moves like ripping out a eyeball or heart. Blood will fly out and can splatter on the screen.
The typical red blood can be turned off or changed to a green color; but more comical blood options include enemies spewing flowers, candy and even pumpkins and carrots for blood.

A few levels take place in dark Egyptian tombs, with a rather creepy atmosphere.
As stated, Serious Sam 3: BFE is much darker than it's predecessors with more instances of violence, nudity and profanity, but the tone is still quite comedic.
The grotesque appearences of the enemies might scare younger players.
