This is an action adventure game in which players assume the role of Nathan Drake, a treasure hunter on a quest to save his friends, find the treasure, and stop a madman from obtaining a great and ancient power. Players can explore ancient ruins in international locales while traversing 3D landscapes embedded with puzzles and traps. Along the way, players will encounter mercenaries/soldiers who will attack with realistic machine guns. Players can brawl with these mercenaries/soldiers, shoot back at them with pistols and rifles, or sneak up on the enemies to perform "stealth kills" (e.g., neck-snapping, choke-holds). During gunfights, brief splashes of blood are emitted from characters; more shots—and thus, more blood—are required to kill a growling ice beast. The action sequences are interspersed with cutscenes that are dramatic, but just as often, humorous in tone; a handful of them contain sexual/suggestive innuendo: "Oh! Is that an ancient Tibetan ritual dagger in your pocket . . . Oh! Maybe I'm just happy to see you" and "Well, so much for foreplay . . ." In one scene, a woman (fully clothed) straddles on top of the central character, places his hands on her hips (he drums his fingers), then kisses him as the camera pans away (to a painting above the bed). In the heat of battle and conversation, the words sh*t , b*tch , and a*s are sometimes exclaimed.
