Tomb Raider Underworld is an action adventure game in which players assume the role of Lara Croft in her quest to rescue her missing mother. Players navigate through mythical islands and historical ruins while fighting human, animal and supernatural enemies. Lara uses various machine guns, grenades, and her own fists to attack adversaries encountered along the way. Faint puffs of red blood are emitted from humans and animals when they are shot. Female characters have somewhat exaggerated physical features and their outfits display moderate amounts of cleavage. Mild profanity (e.g., "damn,""hell," and bloody hell") can be heard during cutscenes.
